I believe there's problem with my profiles since upgrading. How do I fix this? Okay, so I read alot of questions on this but still not clear. I was trying to follow directions on one and lost it and can't find it again because I can't go back - I'm part way to fixing it I think - I found the profiles folder in my finder. (under library, applications support and firefox) Now what do I do? Delete it? and then will it automatically make a new or what?
