Currently, I'm using Fedora 14 on both my desktop and my laptop. Recently, I found myself having website problems with the version of Firefox provided by Fedora, version 3.6.23 so I followed the instructions here: http://www.if-not-true-then-false.co...x-6-on-fedora/
and went right to the latest version, 7.0.1 on both machines.
All is well on the laptop. On the desktop, however, I have a minor problem: the set of buttons available to customize the menus doesn't include one for New Tab, although it's there on my laptop. As I have Tab Mix Plus installed, I asked on their help forum to make sure it wasn't the culprit. After eliminating that possibility, I checked with mozilla.org, and exhausted their possible fixes, most of which were based on the false assumption that the button had been there but had later vanished.
Now I'm checking here to see if anybody's got any ideas that I haven't tried. Assume that I've tried all of the obvious fixes, such as opening in Safe Mode, having Firefox reset itself to the default configuration and so on. About the only thing I haven't tried is reinstalling it, but that's more of a Windows way of doing things and isn't normally worth trying in Linux. Of course, if somebody has a good reason to try it, I will, but I'd like some more opinions first.
