Firefox v3 questions

[yoco]

I have 4 of them :o
Don't know why so much. When I formatted my PC I made backup of my FF profile and when I installed fresh copy of FF I copied the backup in that folder. Could so many profiles cause any problems? Is there a way to find out which one is the right one?!

Usually it's the aforementioned "xxxxxx.default".

But like I said I have four of them. All have .default in the end!

Then keep the biggest one, I suppose. Open all of them and check which one could be yours.
