For a very long time, two titans have been disputing the supremacy in the browsing world, and Firefox has its well-deserved share of fans who would always bring into discussion its outstanding performance and the constant care it has proved over time as regards user needs. Firefox entails all the browsing tools any user out there might need and even more. It is capable of opening as many tabs as you want without making deductions from speed, and the low memory consumption is among the top promises it makes to its users.

That means loading pages is done lightning fast, so you have instant access to all the websites you want to visit. As regards safe browsing, it is definitely not a matter of if, what with the possibility of surfing the Internet via private windows as well as turning to the integrated tools aimed at disabling tracking in case you are worried about the issue.

As regards safe browsing, it is definitely not a matter of if, what with the possibility of surfing the Internet via private windows as well as turning to the integrated tools aimed at disabling tracking in case you are worried about the issue. Apart from that, ensuring that your browsing history is unavailable to unauthorized users is an option, and granting the required permissions to websites you are visiting to use your location, camera, and microphone is entirely up to you.

Moreover, syncing anything ranging from bookmarks to tabs, history, passwords, add-ons, and other settings across multiple devices should help you work without any sort of interruptions, regardless of where and when you decide to do so. Customizing the search options that best cater to your needs should not take more than a couple of seconds, and that includes selecting the default search engine. When it comes to developers, Firefox greets them with a series of tools specifically designed for them.

We love Pull Requests, Bug Reports, ideas, security code reviews or any other kind of positive contribution.

Since we are a small team, however, we do not have the bandwidth to review unsolicited PRs. Please follow our Pull Request guidelines , or we may close the PR. As a small team, we have to prioritize our work, and reviewing PRs takes time.

We receive lots of PRs every day, so if you can keep your PRs small, it helps our small team review and merge code faster, minimizing stale code. Keep in mind that the team is very overloaded, so PRs sometimes wait for a very long time. Please keep in mind that even though a feature you have in mind may seem like a small ask, as a small team, we have to prioritize our planned work and every new feature adds complexity and maintenance and may take up design, research, marketing, product, and engineering time.

That being said, just because we haven't replied, doesn't mean we don't care about the issue, please be patient with our response times as we're very busy. For general development, we recommend the debug build variant. Here's an explanation of each variant:. If you want these variants to be:.

To analyze performance during local development build a production variant locally this could either be the Nightly, beta or release. Otherwise, you could also grab a pre-existing APK if you don't need to test some local changes.

Then, use the Firefox profiler to profile what you need! For more information on how to use the profiler or how to use the build, refer to this how to measure performance with the build. Before you can install any release builds, You will need to sign production build variants: see Automatically signing release builds for details.

Some features are disabled by default when Fenix is built locally. This can be problematic at times for checking performance since you might want to know how your code behaves with those features. The known features that are disabled by default are:. To reduce review turn-around time, we'd like all pushes to run tests locally. Using this hook will guarantee your hook gets updated as the repository changes. This hook tries to run as much as possible without taking too much time.

Before you can run the hook, you'll need to configure Java properly because it relies on command line tools: see our how-to guide. Note: If while pushing you encounter this error "Could not initialize class org. InvokerHelper" and are currently on Java14 then downgrading your Java version to Java13 or lower can resolve the issue.

You can speed up local development by setting a few helper flags available in local. Some flags will make it easy to work across multiple layers of the dependency stack - specifically, with android-components, geckoview or application-services.

With this line, release build variants will automatically be signed with your debug key like debug builds , allowing them to be built and installed directly through Android Studio or the command line. This is helpful when you're building release variants frequently, for example to test feature flags and or do performance analyses.

Nightly, Beta and Release variants are getting published to Google Play and therefore are not debuggable. If you're making changes to these projects and want to test them in Fenix, auto-publication workflow is the fastest, most reliable way to do that. In local. Once these flags are set, your Fenix builds will include any local modifications present in these projects. See a demo of auto-publication workflow in action.

In order to build successfully, you need to check out a commit in the dependency repository that has no breaking changes. The two best ways to do this are:. If you're working with the Nimbus experiments platform, by default for local development Fenix configures Nimbus to not use a server. Firefox Hello was scheduled to be removed in September Functions can be added through add-ons created by third-party developers. As compatibility was not included in the multi-process architecture, XUL add-ons have been deemed Legacy add-ons and are no longer supported on Firefox 57 "Quantum" and newer.

Firefox can have themes added to it, which users can create or download from third parties to change the appearance of the browser. The Firefox add-on website also gives users the ability to add other applications such as games, ad-blockers, screenshot apps, and many other apps. Firefox for Android was equipped with a guest session feature, introduced in , which, when initiated, would memorize ordinary browsing data such as tabs, cookies, and history, but for the duration of the guest session.

The guest session data would be kept even when restarting the browser or device, while deleted only upon a manual exit. The feature was removed, for which Mozilla claims to " streamline the experience ". Firefox has passed the Acid2 standards-compliance test since version 3. Firefox also implements "Safe Browsing," [74] a proprietary protocol [75] from Google used to exchange data related with phishing and malware protection.

For security and privacy reasons, [ which? CDM runs within a " sandbox " environment to limit its access to the system and provide it a randomized device ID to prevent services from uniquely identifying the device for tracking purposes.

The DRM module, once it has been downloaded, is enabled, and disabled in the same manner as other plug-ins. Mozilla justified its partnership with Adobe and Google by stating:. You can also disable each CDM and opt-out of future updates. Firefox allowed for a sandbox security model to manage privileges accorded to JavaScript code, but that feature has since been deprecated. Because Firefox generally has fewer publicly known security vulnerabilities than Internet Explorer see Comparison of web browsers , improved security is often cited as a reason to switch from Internet Explorer to Firefox.

In comparison, exploit code for known, critical security vulnerabilities in Firefox was available for nine days before Mozilla issued a patch to remedy the problem.

A Symantec study showed that, although Firefox had surpassed other browsers in the number of vendor-confirmed vulnerabilities that year through September, these vulnerabilities were patched far more quickly than those found in other browsers, with Firefox's vulnerabilities being fixed on average one day after the exploit code was made available, as compared to nine days for Internet Explorer.

InfoWorld has cited security experts saying that, as Firefox becomes more popular, more vulnerabilities will be found, [98] a claim that Mitchell Baker , president of the Mozilla Foundation, has denied. It is not relational at all," she said. In October , Microsoft's security engineers acknowledged that Firefox was vulnerable to a security issue found in the 'Windows Presentation Foundation' browser plug-in since February of that year.

NET Framework 3. As of February 11, [update] , Firefox 3. Firefox 11, released in January , introduced a 3D page inspector that visualizes web pages' document object model three-dimensionally through WebGL. The feature was accessible from the developer tools. On January 28, , Mozilla was recognized as the most trusted internet company for privacy in In February , plans were announced for Firefox 22 to disable third-party cookies by default. However, the introduction of the feature was then delayed so Mozilla developers could "collect and analyze data on the effect of blocking some third-party cookies.

Additionally, JavaScript could also no longer be disabled through Firefox's preferences, and JavaScript was automatically re-enabled for users who upgraded to 23 or higher with it disabled.

The change was made due to its use across the majority of websites, the potential repercussions on inexperienced users who are unaware of its impact, along with the availability of extensions such as NoScript , which can disable JavaScript in a more controlled fashion.

The following release added the ability to disable JavaScript through the developer tools for testing purposes. Beginning with Firefox 48, all extensions must be signed by Mozilla to be used in release and beta versions of Firefox.

Firefox 43 blocked unsigned extensions but allowed enforcement of extension signing to be disabled. All extensions must be submitted to Mozilla Add-ons and be subject to code analysis in order to be signed, although extensions do not have to be listed on the service to be signed. A Firefox update on May 3 led to bug reports about all extensions being disabled. This was found to be the result of an overlooked certificate and not the policy change set to go into effect on June In Firefox versions prior to 7.

It is enabled by default in development versions of Firefox, but not in release versions. In November , Firefox began using a sandbox to isolate web tabs from each other and from the rest of the system. Its lack of such a feature had previously earned it negative comparisons with Google Chrome and Microsoft Edge.

To use this feature the user must set certain preferences beginning with "network. By setting network. On May 21, , Firefox was updated to include the ability to block scripts that used a computer's CPU to mine cryptocurrency without a user's permission, in Firefox version The update also allowed users to block known fingerprinting scripts that track their activity across the web, however it does not resist fingerprinting on its own.

In Mozilla Foundation Security Advisory —03, the company reported that the CVE - vulnerability type confusion vulnerability in IonMonkey had been detected in the wild and was being actively exploited.

In March , Firefox launched SmartBlock in version 87 to offer protection against cross-site tracking , without breaking the websites users visit. Firefox is a widely localized web browser. The first official release in November was available in 24 different languages and for 28 locales , including British English , American English , European Spanish , Argentine Spanish , Chinese in Traditional Chinese characters and Simplified Chinese characters and in Bengali script.

Firefox source code may be compiled for various operating systems; however, officially distributed binaries are provided for the following:. Firefox 1. Some users reported the 1. In September , a Metro-style version of Firefox optimized for touchscreen use was introduced on the "Aurora" release channel. However, the project has since been canceled as of March [update] , with Mozilla citing a lack of user adoption of the beta versions. Version In April , users of Firefox Support for these operating systems ended in June The first official release Firefox version 1.

Starting with version 4. Firefox was originally released for Mac OS X Since its inception, Firefox for Linux supported the bit memory architecture of the IA instruction set. Firefox for mobile is a web browser for mobile phones, tablets, and PDAs.

It was originally first released for the Nokia Maemo operating system, specifically the Nokia N, on January 28, The former Firefox for Android codenamed Fennec , was a web browser for Android devices, such as mobile phones and tablets. Its user interface was optimized for small screens and tablets.

It included the Awesome Bar, tabbed browsing, add-on support, a password manager, location-aware browsing, and the ability to synchronize with the user's other devices with Firefox Browser using Firefox Sync. One reason given by Mozilla was that prior to iOS 8, Apple had supplied third-party browsers with an inferior version of their JavaScript engine which hobbled their performance, making it impossible to match Safari's JavaScript performance on the iOS platform.

In August , Mozilla launched a new version of its Firefox for Android app, named Firefox Daylight to the public [] and codenamed Fenix , [] after a little over a year of testing. It also added Enhanced Tracking Protection 2.

Firefox is regularly built for the current branch of the operating system, the latest versions are packaged for each release and remain frozen until the next release. Besides official releases, Mozilla provides development builds of Firefox in distribution channels named, in order of most to least stable, "Beta", "Developer Edition" formerly "Aurora", renamed on November 10, [] [] , and "Nightly".

Firefox ESR Extended Support Release is a version of Firefox for organizations and other groups that need extended support for mass deployments.

Each ESR release, based on the regular version released at the same time, is supported for one year. In the past, Firefox was licensed solely under the MPL, then version 1. Additionally, code only licensed under MPL 1. Since the re-licensing, developers were free to choose the license under which they received most of the code, to suit their intended use: GPL or LGPL linking and derivative works when one of those licenses is chosen, or MPL use including the possibility of proprietary derivative works if they chose the MPL.

The crash reporting service was initially closed-source but switched with version 3 from a program called Talkback to the open-source Breakpad and Socorro server.

The name "Mozilla Firefox" is a registered trademark ; along with the official Firefox logo, it may only be used under certain terms and conditions. Anyone may redistribute the official binaries in unmodified form and use the Firefox name and branding for such distribution, but restrictions are placed on distributions which modify the underlying source code.

Mozilla has placed the Firefox logo files under open-source licenses, [] [] but its trademark guidelines do not allow displaying altered [] or similar logos [] in contexts where trademark law applies.

There has been some controversy over the Mozilla Foundation's intentions in stopping certain open-source distributions from using the "Firefox" trademark. To allow distributions of the code without using the official branding, the Firefox build system contains a "branding switch". This switch, often used for alphas "Auroras" of future Firefox versions, allows the code to be compiled without the official logo and name and can allow a derivative work unencumbered by restrictions on the Firefox trademark to be produced.

In the unbranded build, the trademarked logo and name are replaced with a freely distributable generic globe logo and the name of the release series from which the modified version was derived. Distributing modified versions of Firefox under the "Firefox" name required explicit approval from Mozilla for the changes made to the underlying code, and required the use of all of the official branding.

For example, it was not permissible to use the name "Firefox" without also using the official logo. When the Debian project decided to stop using the official Firefox logo in because Mozilla's copyright restrictions at the time were incompatible with Debian's guidelines , they were told by a representative of the Mozilla Foundation that this was not acceptable and were asked either to comply with the published trademark guidelines or cease using the "Firefox" name in their distribution.

The Firefox icon is a trademark used to designate the official Mozilla build of the Firefox software and builds of official distribution partners. Early Firebird and Phoenix releases of Firefox were considered to have reasonable visual designs but fell short when compared to many other professional software packages.

In October , professional interface designer Steven Garrity authored an article covering everything he considered to be wrong with Mozilla's visual identity. Shortly afterwards, the Mozilla Foundation invited Garrity to head up the new visual identity team. The release of Firefox 0.

Included were new icon designs by silverorange, a group of web developers with a long-standing relationship with Mozilla. The final renderings are by Jon Hicks , who had worked on Camino. The panda, according to Hicks, "didn't really conjure up the right imagery" and was not widely known.

In June , Mozilla unveiled a revised Firefox logo, which was officially implemented on version The new logo is part of an effort to build a brand system around Firefox and its complimentary apps and services, which are now being promoted as a suite under the Firefox brand. The logo of the Firefox family uses only the flame component of the logo, and Firefox itself whose logo was revised to match the new branding style is now being referred to in branding as "Firefox Browser".

Firefox 23 — 56, from August 6, to November 13, []. The Nightly logo, used to represent nightly builds of pre-alpha versions. The Aurora logo, used to represent an alpha release. Blue globe artwork, distributed with the source code , and is explicitly not protected as a trademark [].

The logo for the Firefox brand of products and services, as of July It appears as if the fox was removed, but this is not the logo for the browser itself.

Firefox was adopted rapidly, with million downloads in its first year of availability. Firefox continued to heavily market itself by releasing a marketing portal dubbed "Spread Firefox" SFX on September 12, , [] It debuted along with the Firefox Preview Release, creating a centralized space for the discussion of various marketing techniques.

The release of their manifesto stated that "the Mozilla project is a global community of people who believe that openness, innovation and opportunity are key to the continued health of the Internet. The site lists the top referrers.

As a part of the Spread Firefox campaign, there was an attempt to break the world download record with the release of Firefox 3. Three months later, in May , Mozilla officially closed Spread Firefox. Mozilla wrote that "there are currently plans to create a new iteration of this website [Spread Firefox] at a later date.

In celebration of the third anniversary of the founding of the Mozilla Foundation , the "World Firefox Day" campaign was established on July 15, , [] [] and ran until September 15, The Firefox community has also engaged in the promotion of their web browser. Other initiatives included Live Chat — a service Mozilla launched in that allowed users to seek technical support from volunteers.

In December , Internet Week ran an article in which many readers reported high memory usage in Firefox 1. In , Softpedia noted that Firefox 1. Internet Explorer 6 launched more swiftly than Firefox 1. As a workaround for the issue, a preloader application was created that loaded components of Firefox on startup, similar to Internet Explorer.

In January , Lifehacker compared the performance of Firefox 3. Lifehacker timed how long browsers took to start and reach a page both right after boot-up and after running at least once already , timed how long browsers took to load nine tabs at once, tested JavaScript speeds using Mozilla's Dromaeo online suite which implements Apple's SunSpider and Google's V8 tests and measured memory usage using Windows 7's process manager.

They concluded that Firefox 3. They also concluded that Firefox 3. Tom's Hardware summarized their tests into four categories: Performance, Efficiency, Reliability, and Conformance. In the efficiency tests, Tom's Hardware tested memory usage and management. In this category, it determined that Firefox was only "acceptable" at performing light memory usage, while it was "strong" at performing heavy memory usage.

In the reliability category, Firefox performed a "strong" amount of proper page loads. Firefox also scored the highest on the "non-performance" index, which measured memory efficiency, reliability, security, and standards conformance, finishing ahead of Chrome, the runner-up.

Tom's Hardware concluded by declaring Firefox the "sound" winner of the performance benchmarks. In January , a benchmark testing the memory usage of Firefox 29, Google Chrome 34, and Internet Explorer 11 indicated that Firefox used the least memory when a substantial number of tabs were open.

In benchmark testing in early on a "high-end" Windows machine, comparing Microsoft Edge , Internet Explorer, Firefox, Chrome, and Opera, Firefox achieved the highest score on three of the seven tests.

Four different JavaScript performance tests gave conflicting results. Firefox surpassed all other browsers on the Peacekeeper benchmark but was behind the Microsoft products when tested with SunSpider.

Measured with Mozilla's Kraken, it came second place to Chrome, while on Google's Octane challenge it took third behind Chrome and Opera. A similar set of benchmark tests in showed Firefox's JavaScript performance on Kraken and the newer Jetstream tests trailing slightly behind all other tested browsers except Internet Explorer IE , which performed relatively poorly. Edge took overall first place on the Jetstream and Octane benchmarks. As of the adoption of Firefox 57 and Mozilla's Quantum project entering production browsers in November , Firefox was tested to be faster than Chrome in independent JavaScript tests, and demonstrated to use less memory with many browser tabs opened.

Downloads have continued at an increasing rate since Firefox 1. Firefox was the second-most used web browser until November , when Google Chrome surpassed it. Up to early , Firefox was the second-most widely used desktop browser, and that position made it the third-most popular with 3. According to the Firefox Public Data report by Mozilla, the active monthly count of Desktop clients has decreased from around million in to million in Firefox has had much success in some countries and continues to have it; as of June [update] , it is the most popular browser on traditional PCs in e.
