does anyone elce have firefox 3.0 say that firefox.exe has encountered and error and needs to close? it does it alot

I do have it, however have not come across this problem. Try uninstalling it and reinstalling.

I'm not sure but I've heard that Firefox 3.0 is not compatible with Vista. That may be your problem.

it is compatible with vista. i have both ff3.0 and vista, and both work fine for me. just try reinstalling..

Yup, I've noticed this in all the FF3 variants too. It's a FF3 random crash event. It's very common. I'm sorry I can't help you any further. Right now this is in the Firefox dev team's hands. Sorry about all the crashes. :-(

You may want to see if it's any of your extensions causing at least some of the crashes.

Yes. It also has problems loading images. Limit the number of add-ons you have enabled and see if that helps. That's what I have been told.
