Here's what I'm seeing when I browse EF from my work desktop [Ubuntu, Firefox 3.6.16]. The "New Posts" page looks pretty normal, well, apart from the enormous icon and a couple of missing columns.

When I try to do anything else though - reply to threads, PMs, give reputation, etc. - I get something like the second screenshot. Headers only, nothing underneath them. Upshot is that I can read everything, reply to nothing. It's been this way for several days and now it's starting to get annoying.

A problem with the browser cache was my first thought since all other websites (including other vBulletin-based forums) seem OK. So I've tried:
- overriding the cache (i.e. Ctrl-F5)
- clearing the cache
- disabling cache
- disabling memory cache too
Of course restarted FF after each of these, cleared history, cookies, etc. as well. I've also uninstalled various page zoom/image zoom add-ons, on the off chance it might be one of those (doesn't seem likely but given that one of the symptoms was a freakishly-zoomed icon...)

None of it's made any difference.

Suggestions? (Other than "stop modding from work", I mean. )

Funny thing is, I've got Firefox at home (same major version, more or less same add-ons) and all is fine there.

Anyone else had similar problems?
