=== Firefox for iOS ===
Mozilla initially refused to port Firefox to iOS, due to the restrictions Apple imposed on third-party iOS browsers. Instead of releasing a full version of the Firefox browser, Mozilla released Firefox Home, a companion app for the iPhone and iPod Touch based on the [[Firefox Sync]] technology, which allowed users to access their Firefox browsing history, bookmarks, and recent tabs. It also included Firefox's "Awesomebar" location bar. Firefox Home was not a web browser, the application launched web pages in either an embedded viewer for that one page, or by opening the page in the Safari app.<ref>{{cite web |author=Dolecourt, Jessica |date=May 27, 2010 |title=Firefox Home: A not-quite Firefox iPhone app |url=http://reviews.cnet.com/8301-19512_7-20006090-233.html?tag=mncol |url-status=dead |archive-url=https://web.archive.org/web/20121023083335/http://reviews.cnet.com/8301-19512_7-20006090-233.html?tag=mncol |archive-date=October 23, 2012 |access-date=June 2, 2010}}</ref><ref>{{cite web |date=May 26, 2010 |title=Firefox Home Coming Soon to the iPhone |url=http://blog.mozilla.com/blog/2010/05/26/firefox-home-coming-soon-to-the-iphone/ |access-date=June 3, 2010 |archive-date=August 30, 2011 |archive-url=https://web.archive.org/web/20110830032230/http://blog.mozilla.com/blog/2010/05/26/firefox-home-coming-soon-to-the-iphone/ |url-status=live }}</ref> Mozilla pulled Firefox Home from the [[App Store (Apple)|App Store]] in September 2012, stating it would focus its resources on other projects. The company subsequently released the [[source code]] of Firefox Home's underlying synchronization software.<ref name="CW">{{cite web |last=Keizer |first=Gregg |date=September 4, 2012 |title=Mozilla exits iOS as it retires Firefox Home |url=http://www.computerworld.com/s/article/9230877/Mozilla_exits_iOS_as_it_retires_Firefox_Home |access-date=September 14, 2012 |work=Computerworld |archive-date=September 6, 2012 |archive-url=https://web.archive.org/web/20120906234343/http://www.computerworld.com/s/article/9230877/Mozilla_exits_iOS_as_it_retires_Firefox_Home |url-status=live }}</ref>

In April 2013, then-Mozilla CEO [[Gary Kovacs]] said that Firefox would not come to iOS if Apple required the use of the [[WebKit]] layout engine to do so. 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.<ref>{{cite web |last=Bilton |first=Ricardo |date=March 10, 2013 |title=Mozilla wants to bring Firefox to iOS, but mean ol' Apple's standing in its way |url=https://venturebeat.com/2013/03/10/mozilla-firefox-ios/ |url-status=live |archive-url=https://web.archive.org/web/20161018233945/http://venturebeat.com/2013/03/10/mozilla-firefox-ios/ |archive-date=October 18, 2016 |access-date=September 18, 2016 |website=VentureBeat}}</ref> Apple later opened their "Nitro" JavaScript engine to third-party browsers.<ref>{{cite web |last=Shankland |first=Stephen |date=June 4, 2014 |title=iOS 8 grants new power to rival browsers, Web-based apps |url=https://www.cnet.com/news/ios-8-grants-new-power-to-rival-browsers-web-based-apps/ |url-status=live |archive-url=https://web.archive.org/web/20160901151602/http://www.cnet.com/news/ios-8-grants-new-power-to-rival-browsers-web-based-apps/ |archive-date=September 1, 2016 |access-date=September 18, 2016 |publisher=CNET}}</ref> In 2015, Mozilla announced it was moving forward with Firefox for iOS, with a preview release made available in New Zealand in September of that year.<ref>{{cite web |date=September 3, 2015 |title=Firefox for iOS Now Available for Preview |url=https://blog.mozilla.org/futurereleases/2015/09/03/firefox-for-ios-now-available-for-preview/ |url-status=live |archive-url=https://web.archive.org/web/20150904142955/https://blog.mozilla.org/futurereleases/2015/09/03/firefox-for-ios-now-available-for-preview/ |archive-date=September 4, 2015 |access-date=September 7, 2015}}</ref><ref>{{cite web |last=Clarke |first=Gavin |date=September 4, 2015 |title=Fruity Firefox: Mozilla caves to Apple, unveils iOS-friendly browser |url=https://www.theregister.co.uk/2015/09/04/mozilla_reveals_firefox_ios_preview_apple/ |url-status=live |archive-url=https://web.archive.org/web/20150906221803/http://www.theregister.co.uk/2015/09/04/mozilla_reveals_firefox_ios_preview_apple |archive-date=September 6, 2015 |access-date=September 7, 2015 |website=[[The Register]]}}</ref><ref>{{cite web |date=May 22, 2015 |title=Update on Firefox for iOS |url=https://blog.mozilla.org/futurereleases/2015/05/22/update-on-firefox-for-ios/ |url-status=live |archive-url=https://web.archive.org/web/20150905091030/https://blog.mozilla.org/futurereleases/2015/05/22/update-on-firefox-for-ios/ |archive-date=September 5, 2015 |access-date=September 7, 2015}}</ref> It was fully released in November later that year.<ref>{{Cite web |last=Calimlim |first=Aldrin |date=November 12, 2015 |title=Finally, Mozilla's Firefox Web browser is now available on iOS |url=http://appadvice.com/appnn/2015/11/finally-mozillas-firefox-web-browser-is-now-available-on-ios |url-status=live |archive-url=https://web.archive.org/web/20161005130721/http://appadvice.com/appnn/2015/11/finally-mozillas-firefox-web-browser-is-now-available-on-ios |archive-date=October 5, 2016 |access-date=September 6, 2020 |website=AppAdvice |language=en}}</ref> It is the first Firefox-branded browser not to use the [[Gecko (layout engine)|Gecko]] [[Browser engine|layout engine]] as is used in Firefox for [[Mozilla Firefox|desktop]] and [[Firefox for mobile|mobile]].

The Firefox port for OpenBSD is maintained by Landry Breuil since 2010. 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. In 2017, Landry began hosting packages of newer Firefox versions for OpenBSD releases from 6.0 onwards, making them available to installations without the ports system.<ref>{{cite web |url=https://undeadly.org/cgi?action=article&sid=20170425173917 |publisher=OpenBSD Journal |access-date=December 18, 2017 |date=April 25, 2017 |title=The many ways of running firefox on OpenBSD |archive-url=https://web.archive.org/web/20171228112231/https://undeadly.org/cgi?action=article&sid=20170425173917 |archive-date=December 28, 2017 |url-status=live}}</ref>
