Firefox only runs very slowly I get "403 forbidden" message whenever I connect. How can I fix it?

Firefox has turned very slowly on my Mac (version 10.6.8). Very, very slowly. In addition, whenever I connect I get a "403 forbidden" message for my websites favorite, my email, etc. How can I fix it?

I tried to open Firefox without Add - ons and that did not help at all.

I also uninstalled MacKeeper, but which did not help either.
