More on that Ubuntu/Firefox bug

Okay, this should hopefully be the last word from me on this. I’ve discovered there’s a bug report on this issue in Ubuntu’s Bugzilla system, which has some pretty informative comments.

I uninstalled Tabbrowser, Web Developer Toolbar and Image Zoom extensions (as well as FireFTP, but that’s just because I never use it anymore/it’s always been too clunky), then restarted Firefox — presto, the Preferences work again, as does myriad other things. I’ve reinstalled the Web Developer Toolbar extension as well as Image Zoom, and restarted, and now everything appears to be working as normal again.
