Mozilla judged that third-party-installed add-ons were problematic, taking away user control, lagging behind on compatibility and security updates, slowing down Firefox startup and page loading time, and cluttering the interface with unused toolbars. Add-ons installed by third-party programs were disabled by default, but user-installed add-ons were enabled by default. Upon installation, a dialog box prompted users to enable or disable the add-ons. įirefox 8 was released on Novem and prompts users about any previously installed add-ons. Trailing slashes on domains are also hidden, for example: becomes. Some URLs are trimmed in the address bar, so the ' scheme no longer appears, but ' is still displayed. Firefox 7.0.1 was released a few days later to fix a rare, but serious, issue with add-ons not being detected by the browser. įirefox 7 was released on September 27, 2011, and uses as much as 50% less RAM than Firefox 4 as a result of the MemShrink project to reduce Firefox memory usage.

This update also brought the infamous feature that caused JavaScript entered in the address bar to not run. įirefox 6 was released on August 16, 2011, introducing a permissions manager, new address bar highlighting (the domain name is black while the rest of the URL is gray ), streamlining the look of the site identity block, a quicker startup time, a ScratchPad JavaScript compiler, and many other new features. Mozilla also integrated the HTML5 video WebM standard into the browser, allowing playback of WebM videos. Firefox 5 has significantly improved the speed of web-related tasks, such as loading pages with combo boxes or MathML. Firefox 5 is the first release in Mozilla's new rapid release plan, matching Google Chrome's rapid release schedule and rapid version number increments. Firefox 5 through 9įirefox 5 was released on June 21, 2011, three months after the major release of Firefox 4. Chrome switched to a four-week cycle a year later.

In 2020, Firefox moved to a four-week release cycle, to catch up with Chrome in support for new web features. Mozilla uses A/B testing and a staged rollout mechanism for the release channel, where updates are first presented to a small fraction of users, with Mozilla monitoring its telemetry for increased crashes or other issues before the update is made available to all users. In 2017, Mozilla abandoned the Aurora channel, which saw low uptake, and rebased Firefox Developer Edition onto the beta channel. For corporations, Mozilla introduced an Extended Support Release channel, with new versions released every 30 weeks (and supported for 12 more weeks after a new ESR version is released), though Mozilla warned that it would be less secure than the release channel, since security patches would only be backported for high-impact vulnerabilities.

For example, the nightly channel would feature a preliminary unstable version of Firefox 6, which would move to the experimental 'Aurora' channel after preliminary testing, then to the more stable 'beta' channel, before finally reaching the public release channel, with each stage taking around six weeks. The release process was split into four 'channels', with major releases trickling down to the next channel every six to eight weeks. Ars Technica noted that this new cycle entailed 'significant technical and operational challenges' for Mozilla (notably preserving third-party add-on compatibility), but that it would help accelerate Firefox's adoption of new web standards, feature, and performance improvements.

In March 2011, Mozilla presented plans to switch to a faster 16-week development cycle, similar to Google Chrome. Main article: Firefox early version history Rapid releases This was gradually accelerated further in late 2019, so that new major releases occur on four-week cycles starting in 2020. Starting with version 5.0, a rapid release cycle was put into effect, resulting in a new major version release every six weeks. Firefox was created by Dave Hyatt and Blake Ross as an experimental branch of the Mozilla browser, first released as Firefox 1.0 on November 9, 2004.
