I've been working on a project and now after the Firefox 5 update on Ubuntu Linux 11.04 64-Bit, the editor doesn't display. On Windows, it shows fine. I'm thinking it's a Firefox issue since the editor worked fine today before the update with Firefox 4. All the other browsers on Ubuntu Linux showed it fine, but Firefox 5.
This is a major problem, because Firefox 5 is the default browser on Ubuntu and has a great market share across all Operating Systems.

The area for the editor stays blank. I noticed the problem first in FogBUGZ and then came here.
I can go to other browsers and it's fine. I can go to another computer that has Windows Server 2008, 64-bit and run Firefox 5 there, and it works fine.
So I'm not sure that it's the browsers problem, but it's not necessarily the servers problem either.
I thought that it could have been a browser Add-On. Disabled them and the problem persists. Flushed my cache, deleted cookies pertaining to the site... Nothing I've done makes the editor show up.
