Firefox 2 and Gecko 1.8 End of Life
vm writes "According to Mozilla and other sources, Firefox 2 and Gecko 1.8 will soon be left behind some time in mid-December. The end result: no future security or stability updates. This will affect Thunderbird 2, SeaMonkey 1.1, Camino 1.5, and any other projects based on Gecko 1.8. So, if you haven't already upgraded, there's no time like the present."
Thunderbird 2 is effected by this, but afaik there is no Thunderbird 3.
Is this is a death sentence for the project?
See the mozilla.dev.planning thread in which the Firefox 2 EOL was first discussed. Yes, just dropping support altogether would cause problems for products like SeaMonkey, Thunderbird e.a. (which haven't yet shipped a version based on 1.9), and that's why that won't happen. Firefox 2 might be unsupported, but necessary security fixes will continue to be identified and backported to the Mozilla 1.8.1 branch, so that those products can continue to release security updates for a while until after their next versions have shipped (hopefully by the end of Q1 2009).
That is the issue with Firefox/Mozilla. They seem to ignore the enterprise requirements, how companies do things etc. As result, IE enjoys its kingdom on Windows desktop.
For example, while entire thing is documented, even open source package makers exist, they refuse to ship MSI packages. MSI is the Windows Native installer. It is not so different from shipping tar.gz to Redhat Enterprise and expect those sysadmins sit and convert them to RPM. It is same deal on OS X too while OS X doesn't have that many enterprise users. Normally, a .pkg should be provided.
Here is the entirely open source maker for MSI files coming from MS employee directly. (No moonlight/mono deal)

No, Windows admins won't monkey around 2000 terminals to run "setup.exe" files. Some guys spare significant amount of time building their own MSI files just to satisfy Firefox fans.
If you can't run FF3, you better convert to Konqueror or Opera if they really stop security updates. Firefox is really popular and lots of 2.x users still exist. Black hats will sure use that advantage.
