You realize add-on signing is super easy and if you have an add-on that won't run because it's unsigned you can just sign it yourself? You don't need to use a version two years old and has tons of known security issues. And add-on signing was critical because millions of users don't know how to revert the hijacking we worked to prevent. IE was just one of a number of web browsers that existed then. The browser we know as Firefox started as Phoenix 0. Due to Phoenix Bios existing Mozilla changed name to Firebird for 0.
Then due to the open source Firebird SQL already being around for a bit Mozilla decided to not have confusion between the two and changed it to Firefox starting at Release version 0. Firefox did not start at version 1. There were other browsers like Netscape and the Mozilla suite started in which has been continued as SeaMonkey ever since Mozilla dropped it at version 1.
There also was Camino which started February 13, and ended March 14, Safari was January And Opera has been in various development status since as early as April Nope, not a codename but a development Channel.
Mozilla has not used codenames since the versions before Firefox 4. Also older versions do not have the security fixes that have been put in since, many of which are critical. Good to know. Got more to do with my life. Or just say "this list does not exist" which I find hard to believe, since there is a huge list since firefox 0.
Why do you need an older version? Old versions are not supported anymore and you should use the latest. If it's not a motive enough for you guys: then don't help which translates into "stop asking irrelevant questions and giving half relevant information, cause that's how the topic is going since the beginning".
If it doesn't exist, or you're declining to publish it, please state so the topic can be closed and I can migrate to chrome. Older EOL versions do not have the security fixes the recent versions have so hopefully you are not planning to use a random old developer edition build for all your browsing. Search Support Search.
