firefox will not start and profile manager will not start

more options

This has happened on two accounts on my laptop. I am running windows 7, 64 bit and firefox 18.0. Firefox had been running on this machine for several years without incident, but suddenly when I try to start firefox, it will not start. The little wait icon spins for about a second then disappears without starting firefox. Other browser will start and run. I reboot and when I click on the icon to start firefox nothing happens. I tried to start the profile manager as seen in the knowledge base, but nothing starts either. I switched to another account on this computer and firefox started and ran for about a week, until today where it just stopped working. I have not tried to reinstall firefox as the message boards say this will not help. Any ideas?

Hello scjsb, can you start firefox in safe mode by holding down the shift key while starting Firefox ?

do you have a crash Report ID ?

thank you

Thanks for your help. I had tried starting Firefox in safe-mode before I posted this request, but it did not work. I tried to restore the system to an earlier version, but that made everything worse. Two accounts were unusable and one sort of worked, so I reloaded the operating system and now firefox works, for how long, I don't know. But thanks again for your suggestion.

I have this problem 3

Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.

I have a dual boot machine [XP64 & WIN 7]. I've been having this problem in XP64. Unfortunately, the dual boot doesn't allow the safe mode boot into XP; only Win 7.

However, since my post I installed Firefox 19. It is running [smiles].

Thanx

I had this problem as well. Did all of the above but only installing Firefox 19 solved the problem.
