I know that a lot of people are experiencing crashed with FF3 so I guess the same goes for FFP3. My crashes happen sometimes when I close FFP3, but that's not the point - I'm sure it'll be eventually fixed.
What I don't get is why it always gives me an error when trying to send the error report - it says it could send it. Any ideas why?
Upgrade to FF 3.0.1 here
I experienced a lot of crashes in 3.0 but it didn't happen again when I upgraded to 3.0.1
As for the error report not sending, I think that's just another problem in 3.0
