@Barbara: Thanks, at least I got a confirmation whether it was me or not.

As for reloading, I did try that, using F5 and shift+F5, I had already cleared cache earlier, but lemme try a few more things.

Edit:Updating to FF4 did the trick! The wierd rollback seemed to happen around the same time FF4 came out (or maybe when you guys updated the website for it), so... yea, figures.
