On an irregular basis, sometimes 4 or 5 times a day or sometimes once a week, when I start up Mozilla Firefox it will only start in safe mode. I have to restart the computer (HP TouchSmart desk top) to get it to run correctly. If I try Internet explorer, when it's doing this, it keeps opening up new windows until it won't open up anymore.
I have all my updates up to date, anybody got any ideas. I run Norton antivirus which also automatically updates.
Thanks in advance Mike
