Today when I loaded up firefox, heaps of things were missing and some things wern't working. For example, I had custimized my navigation buttons, all of the custimizations are missing, I fixed it back up but when I closed it and reopened Firefox they were gone again. I can't bookmark pages, the Bookmark dialog pops up when I hit enter or okay it doesn't dissapear it just stays there. I have to click cancel or the X to get it to close, it doesn't bookmark the page in my list either. I havn't changed the software or anything yesterday or today and it was working fine yesterday, what could have caused this and can I fix it?
I have Firefox, 184.108.40.206, It isn't the latest so should I upgrade it?
