I've been using RTM on Firefox for a long time, but today upon logging in the layout is entirely messed up, with everything essentially going downwards. I changed no settings to my knowledge.

Problem is not there in Chrome. I tried disabling plug-ins and starting in safe mode, but the problem persists.

One strange thing is that at the top I have a "offline" icon and two arrows - one for going online, the other for going offline - and a spinning dial that says "synchronizing". I do not have Google Gears or anything like that, so I'm not sure what this is about since I thought RTM doesn't have an offline function.

I also tried changing a setting or two (switching from http to https), but nothing worked.

Thanks for any help!
