Since I installed the latest update, my computer occasionally tells me it is still logged on whenit is not. I have to restart to clear. How do I fix this.

Question

When I am logged onto to Firefox - I sign off. After a minute or two, I try to log on again - it tells me it is already running (it is not) which I confirm by looking at "all programs" (which does not show it running). The amount of wait between signing off and trying to sign on again does not effect ability to log on. The only way to be able to sign back onto Firefox is to "restart".

Answer 1

I think you are getting your terms mixed up. Logging on/off is when
you access a web page, or starting the computer. Are you trying to
say after shutting down Firefox, it won't restart?
From what I have been reading from other posts on this forum, the issue may
be caused by the clear history settings.
Press the '''<Alt>''' or '''<F10>''' key to bring up the tool bar.
Then '''Tools > Options > Privacy'''.
The button next to '''History''', select '''Use Custom Settings'''.
At the bottom of the page, turn on '''Clear History When Firefox Closes.'''
At the far right, press the '''Settings''' button. Turn on ONLY '''Cache''' and
'''Form And Search History''' leaving the others off.
This is not a cure but will make it easier if Firefox locks up.
