Firefox version history#Rapid releases

{{Cleanup|date=May 2023|reason=Lots of re-used words, grammar errors, many sources to Mozilla's release note pages that don't have any secondary sourcing.}}

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. Starting with version 5.0, a rapid release cycle was put into effect, resulting in a new major version release every six weeks. This was gradually accelerated further in late 2019, so that new major releases occur on four-week cycles starting in 2020.{{cite web |last1=Kothari |first1=Ritu |last2=Or |first2=Yan |title=Moving Firefox to a faster 4-week release cycle |url=https://hacks.mozilla.org/2019/09/moving-firefox-to-a-faster-4-week-release-cycle/ |website=Mozilla Hacks |access-date=26 February 2020 |archive-date=February 20, 2020 |archive-url=https://web.archive.org/web/20200220060903/https://hacks.mozilla.org/2019/09/moving-firefox-to-a-faster-4-week-release-cycle/ |url-status=live }}

Early versions

Rapid releases

In March 2011, Mozilla presented plans to switch to a faster 16-week development cycle, similar to Google Chrome. 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.{{Cite web |last=Paul |first=Ryan |date=2011-03-18 |title=Mozilla outlines 16-week Firefox development cycle |url=https://arstechnica.com/information-technology/2011/03/mozilla-outlines-16-week-firefox-development-cycle/ |access-date=2023-04-22 |website=Ars Technica |language=en-us |archive-date=April 22, 2023 |archive-url=https://web.archive.org/web/20230422162557/https://arstechnica.com/information-technology/2011/03/mozilla-outlines-16-week-firefox-development-cycle/ |url-status=live }}{{Cite web |last=Paul |first=Ryan |date=2011-02-14 |title=Is Mozilla's 2011 roadmap unrealistically ambitious? |url=https://arstechnica.com/information-technology/2011/02/is-mozillas-2011-roadmap-unrealistically-ambitious/ |access-date=2023-04-22 |website=Ars Technica |language=en-us |archive-date=April 22, 2023 |archive-url=https://web.archive.org/web/20230422162558/https://arstechnica.com/information-technology/2011/02/is-mozillas-2011-roadmap-unrealistically-ambitious/ |url-status=live }} This plan was implemented in April 2011.{{Cite web |last=Siegler |first=M.

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.{{Cite web |last=Anthony |first=Sebastian |date=2017-04-18 |title=Firefox kills off Aurora channel to speed up release of new features |url=https://arstechnica.com/information-technology/2017/04/firefox-aurora-killed-off/ |access-date=2023-04-22 |website=Ars Technica |language=en-us |archive-date=April 22, 2023 |archive-url=https://web.archive.org/web/20230422162557/https://arstechnica.com/information-technology/2017/04/firefox-aurora-killed-off/ |url-status=live }}{{Cite magazine |last= |date=April 14, 2011 |title=How to Use Firefox's New 'Aurora' Release Channel |language=en-US |magazine=Wired |url=https://www.wired.com/2011/04/how-to-use-firefoxs-new-aurora-release-channel/ |access-date=2023-04-22 |issn=1059-1028}} 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.{{Cite web |last=Kingsley-Hughes |first=Adrian |date=September 22, 2011 |title=Mozilla attempts to appease enterprise users with talk of 42-week Firefox release cycle |url=https://www.zdnet.com/article/mozilla-attempts-to-appease-enterprise-users-with-talk-of-42-week-firefox-release-cycle/ |access-date=2023-04-22 |website=ZDNET |language=en |archive-date=April 22, 2023 |archive-url=https://web.archive.org/web/20230422162557/https://www.zdnet.com/article/mozilla-attempts-to-appease-enterprise-users-with-talk-of-42-week-firefox-release-cycle/ |url-status=live }}

In 2017, Mozilla abandoned the Aurora channel, which saw low uptake, and rebased Firefox Developer Edition onto the beta channel.{{Cite web |last=Protalinski |first=Emil |date=2017-04-17 |title=Mozilla kills Firefox Aurora channel, builds will move directly from Nightly to Beta |url=https://venturebeat.com/business/mozilla-kills-firefox-aurora-channel-builds-will-move-directly-from-nightly-to-beta/ |access-date=2023-04-22 |website=VentureBeat |language=en-US |archive-date=April 22, 2023 |archive-url=https://web.archive.org/web/20230422162557/https://venturebeat.com/business/mozilla-kills-firefox-aurora-channel-builds-will-move-directly-from-nightly-to-beta/ |url-status=live }} Mozilla uses A/B testing{{Cite web |last1=Kothari |first1=Ritu |last2=Or |first2=Yan |date=September 17, 2019 |title=Moving Firefox to a faster 4-week release cycle |url=https://hacks.mozilla.org/2019/09/moving-firefox-to-a-faster-4-week-release-cycle |access-date=2023-04-22 |website=Mozilla |language=en-US |archive-date=May 21, 2023 |archive-url=https://web.archive.org/web/20230521004831/https://hacks.mozilla.org/2019/09/moving-firefox-to-a-faster-4-week-release-cycle/ |url-status=live }} 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.

Upon installation, a dialog box prompted users to enable or disable the add-ons. Add-ons installed by third-party programs were disabled by default, but user-installed add-ons were enabled by default. 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.{{cite web |url=https://www.cnet.com/news/firefox-8-cracks-down-on-add-ons/ |title=Firefox 8 cracks down on add-ons |website=cnet |date=November 9, 2011 |access-date=September 17, 2021 |archive-date=September 17, 2021 |archive-url=https://web.archive.org/web/20210917031808/https://www.cnet.com/news/firefox-8-cracks-down-on-add-ons/ |url-status=live }} Added option in preferences to lazy load session tabs (prior to that it could be switched by config setting since version 4.0 beta 7{{Cite web |date=2010-09-17 |title=Cascaded Session Restore + a Hidden Bonus |url=https://zpao.com/posts/cascaded-session-restore-a-hidden-bonus/ |access-date=2024-06-19 |website=zpao.com |archive-date=June 19, 2024 |archive-url=https://web.archive.org/web/20240619223847/https://zpao.com/posts/cascaded-session-restore-a-hidden-bonus/ |url-status=live }}).{{Cite web |date=2011-08-17 |title=max_concurrent_tabs is Dead; Long Live restore_on_demand |url=https://zpao.com/posts/max-concurrent-tabs-is-dead/ |access-date=2024-06-19 |website=zpao.com |archive-date=June 19, 2024 |archive-url=https://web.archive.org/web/20240619223847/https://zpao.com/posts/max-concurrent-tabs-is-dead/ |url-status=live }}

Firefox 14 was released on June 26, 2012, for mobile devices only, just outside the regular release schedule of the web browser.{{cite web |url=https://www.ghacks.net/2012/07/17/firefox-14-0-1-available-why-there-wont-be-a-firefox-14-0-release/ |title=Firefox 14.0.1 available, Why there won't be a Firefox 14.0 release |last=Brinkmann |first=Martin |website=ghacks |date=July 17, 2012 |access-date=July 17, 2012 |archive-date=July 18, 2012 |archive-url=https://web.archive.org/web/20120718194258/http://www.ghacks.net/2012/07/17/firefox-14-0-1-available-why-there-wont-be-a-firefox-14-0-release/ |url-status=live }} In order to sync the version numbers of the desktop and mobile versions of Firefox, Mozilla decided to release version 14.0.1 for both mobile and desktop on July 17, 2012, instead of Firefox 14 version 14.0 for the desktop and version 14.0.1 for mobile devices.

Firefox 14 introduces a new hang detector (similar to how Mozilla currently collects other data) that allows Mozilla to collect, analyze, and identify the cause of the browser freezing/hanging.
