I
always use the Flash Uninstaller before I update Flash.
(Will try it again once more and will also uninstall avast! with aswclear and make a clean install... again.)
I checked mms.cfg and it says:
AutoUpdateDisable=0
SilentAutoUpdateEnable=0Adding
ProtectedMode=0should not be necessary, because mozillaZine states 11.3.300.262 disables Protected Mode by default. I made an inquiry on the newsgroup
mozilla.support.firefox and two posters reacted avast is not causing any problem. I'm almost ready to install Avira...
Edit: Booted in Safe Mode, uninstalled avast (again), uninstalled Flash, reinstalled, rebooted several times in between. Nothing - besides disabling avast or shutting down the Behavior Shield - helps. I also tried disabling Online Armor Free, but that didn't help either. I don't know what to do anymore (instead of dumping avast and installing Avira instead).
