Can't post using Firefox 3

Downgrade to FF2, silly early adopters

Can't expect websites to have already developed workarounds for the quirks of new buggy browsers

Uh, FF3 has been in beta/developer release for months... 3.0.1 is the current live version.
And do you consider that perhaps it's this forum software that's buggy, and that the new tighter code in FF3 is just revealing behavior that already existed?
So yeah -- downgrade to the buggy FF2 if you don't like a more secure, faster, and stable browsing experience... I guess...
