I have HP pavilion A6511 running vista home premium. ad-aware, spywareblaster, AVG, zonealarm AMD dual core 4600+, 360gig HDD, 2 gig ram.
the problem is firefox. after opening 2 or 3 times running ok it then refuses to open from the desktop icon. I have to restart the pc and the same thing happens.
I have unistalled firefox twice including all profile folders etc. today i reinstalled windows from the restore partition.
I have searched for solutions on mozilla and www but nothing seems to work or the fault is not covered. suggestions include uninstalling zonealarm, which i don't want to do, AVG search safe is suggested as a problem but i am not willing to unistall anything except the problem which is firefox.
I have a laptop running the same applications/OS and firefox works so this is puzzling me.
Have you looked in the Event log under Applications for Firefox references? Tried Firefox (Safe Mode)? Tried Firefox using a new or other account (I mean Windows account, I'm not confusing the term with firefox profiles) ?
Tried Portable Firefox (just create any folder you like in your Documents folder and install Portable Firefox there)?
Any add-ons installed? Firefox Safe Mode should eliminate add-on problems.
To be sure the firewall is not the problem you will have to uninstall it temporarily, just disabling it might not be enough.
