I can't save any changes in Firefox. I want a blank starting page, not to be asked about passwords everytime, adjust my security etc. Nothing works. I go to Tools, make the changes, and the next time I open Firefox, it is as if nothing has been saved.

I have even tried to uninstall and install it, but that doesn't work either. Should I go for Chrome forever, and just unistall Firefox, because this is so frustrating.
