The Mozilla Foundation just recently announced that they have started a new program “End Of Life” meaning 6 months after a new version of one of their product is released the end of life for the previous version will cease 6 months later. Mozilla said that it is going to stop making patches and updates for Firefox 2.0 and the gecko 1.8 layout engine in mid-December of 2008.
Why’d You let go of my gecko!
Even though the life of Gecko 1.8 is coming to its final stage in life; Mozilla assured developers that third parties will still be able to fix the software for Gecko 1.8. Gecko 1.8 is the layout engine for Firefox 2.0 and thunderbird 2.0. In layman's terms it is the underbelly of Firefox 2.0 and Thunderbird 2.0; it's what makes them work.
The director of Firefox; Mike Beltzner stated that the end of life “doesn't mean 'everyone stop coding and doing reviews', more that 'we don't have a team doing weekly triage on blockers and milestone releases',"
So there you go the end of support for Firefox 2.0 is coming to a swift end very soon with Mozilla encouraging people to update to Firefox 3.0.
