I've been having trouble with Firefox 3 (whichever is the latest revision, and the one before it) and Minefield lately and was wondering if anyone else has come across the same problem.
It seemed to occur even after disabling all of my add-ons (all one of them) so I don't think that's it.
Sometimes, when opening a page (from a google search, not from a site a regularly visit) or when submitting a form (such as the login form for this site), it crashes. I haven't yet tried either in their Safe Mode.
And for reference, I'm using Windows 7 x64 build 6801, and I've used the Blue Badge tool to enable the Super Bar and other features.
