Sometimes, I'll have a couple tabs open, and in one of them, I'll be loading a page that seems to take a little longer to load. It's not a specific page or a specific site, and never actually starts to load.
Just about when I'd expect it to timeout and give me a error message, Firefox instead opens a blank tab all on it's own. And then another, and another and another - to infinity. They open in about the same time it takes to close a tab, and there's no way to stop them from opening once it starts. If I close down the window, Firefox will open up a new window and continuing making blank tabs. I have to go to Task Manager and end the firefox process to stop it (and if I Restore Previous Session after I restart firefox, the blank tabs come right back.)
Has this happened to anyone else? I've tried googling, but I guess I haven't hit on the right search words. It's happened on different computers running different versions of windows and different versions of firefox, so I'm lost.
My first thought would be to check for a stuck key on your keyboard. But if it's happened on multiple computers that's out.
Do you use any/some/lots of Firefox extensions? Are any or all of them common to the various computers? If so, try disabling them one by one.
Otherwise it could potentially be some sort of malware that's misbehaving, or Firefox choking on a particular page's content, but I assume you would have pointed out any other trends you might have noticed like it happening to the same page repeatedly or something.
I do use the open source googlebar extension on all the installs I'm having the problem. Maybe that's it? I need some google bar around to help me with translations, but I'll try using the official one and see if it stops.
I don't know why it's bothering me so much, but on all of Google's websites (main page, GMail, Blogger, etc.) the font is just slightly larger than it has been previously ... I didn't change any of my personal settings (as far as I know)
