Firefox will not start, even though it is listed in my processes in task manager. Can't get profile manager to start either.

I have tried the following to no avail: - try to start FF in Safe Mode, doesn't load - started Windows Vista in Safe Mode, FF still does not load - turned off Kaspersky AV, FF still does not load - uninstalled FF, cleaned out user/####/AppData/Mozilla/Firefox folder, as well as ProgramFiles/Mozilla/Firefox folder, and cleaned our Registry manually from all references to Firefox. Downloaded FF 3.6.3, installed. still does not load - whatever i seem to do, does not fix the problem. When I try to start Firefox, no window appears. I can see the process starting in my task manager. I can "end process" and try to start the program again by double-clicking program icon. Process starts in task manager, but no app window appears.

I am frustrated and have just wasted 2+hours of my night trying to get this to work. Downloaded Google Chrome, unless there is a fix for FF (which I would prefer to use), i will have to switch to Chrome.

I can't pinpoint when this trouble started, but may have been after a recent Windows Update. I already did a System Restore to a restore point about 5 days ago (the oldest one available to me, and I believe that was before the FF trouble started). This has not helped either.

I have run a full virus scan with Kaspersky and a Full scan with Windows Defender. Nothing came up.

Anyone else been able to find a solution to this?

I found a way to make it work somehow but not really fixing the error... one day when I got really pissed off because FF just won't open, I clicked the icon and killed the enter button, then multiple FF windows appeared. I tried to open it with just a single hit of the enter or double clicking but it won't work anymore, but repeatedly clicking the enter button (mine works with just 3 hits, sometimes 6) seem to open it. And until now, I have no technical explanation for this.
