The problem is with my Application Data folder. My Firefox shown a message stating "Could not initialize the application's security document" and it stopped showing bookmarks and history. I restarted my PC after backing up my bookmarks.

I get a message as my desktop showed saying that application has unsuccessful to begin. I then obtain a message saying my ati catalyst control center has failed.
As I have reinstalled Firefox and catalyst control center and drivers a two times and have left CCC off fully. I ran an error check on my drive. I still unsuccessful to open my Firefox bookmarks and history and I get that same error message at start.

Therefore previous to this had all occurred I was installing different games and alcohol 120%. After a couple failed installs I had to go through and delete some files and it is probable I accidentally deleted somewhat anywhere I shouldn’t have. The definite last thing I did before I noticed the problems, was install a patch on MechWarrior 4. I have uninstalled that game since.
I have vista 64 btw.
