Yesterday - sep 29 I got a message saying to install a security and stability update for firefox. The update seemed to work fine at first but I then tried to use the adobe plugin - the reader for pdf documents not the flash player. It made my computer freeze and after restarting the computer firefox would not open! I did a system restore and that did not fix the issue. I finally had to go into safe mode and reinstall firefox. Googling suggested the adobe plugin was to blame but I had no issues until I updated firefox. I am getting messages to update again but am ignoring them now. Is there some sort of conflict with the update and adobe?
