Hi. I also had the problem, and also tried to remove the web developper extension.
FYI, it also crashed here when I removed the extension (From Tools / Extension dialog), but then when I satarted firefox again, the extension was gone, and now it looks as if the bug has gone... This is at least a kind of workaround... Hope this helps. > I also had web-developer extension installed, so I tried to > deinstall it.
