Sorry about the delay.
Even though I am subscribed to this thread, I don't remember receiving a notification about your message.
I assume that for some reason, you can't close Firefox by:
- Clicking the "Close" button?
- Choosing "Exit" from the menu (orange Firefox button)?
If you kill Firefox using the Task Manager (or Process Explorer), the Session Manager file (sessionstore.js) will have an entry saying FF is still running.
The next time you start Firefox, it will assume that it crashed and it may offer to restore your previous session.
I sometimes have to kill Firefox (using Process Explorer).
This is usually because Adobe Flash player tries to start running during the shutdown sequence
, which causes Firefox to lock up.
I haven't experienced the behaviour you describe. Have you tried reinstalling Firefox?
If that doesn't work, you may need to backup certain files and totally uninstall and reinstall Firefox.
I can provide a list of those files, if you need them.
