Firefox 3.5

[caravel]

So I'm the only one who's got it buggy.

Edit: A reinstall later and it's all perfect!

Any problems between major updates are usually fixed by a clean reinstall - and anything a reinstall doesn't fix can be fixed by deleting your user profile, plugins etc, this is usually in ~/.mozilla/firefox/ or usually "C:\Documents and Settings\your user\Application Data\Mozilla" for windows users. It means you'll have to re-do all of your customisations of course.

-Edit: Any problems with specific websites are usually cured by clearing the cache.
