Very nice tutorial

Thanks. :)

I hope people find it useful and easy to follow.

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.

sessionstore.js

...
{"state":"running","lastUpdate":1350784513943,"startTime":1346516225279,"recentCrashes":0},"scratchpads":[]}

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. :)

Thank you lehnerus2000

I have to use a batch file to kill firefox in a autorun program. I used Taskkill to kill it.

I tried to re-install a fresh firefox that doesn't have any add on or plugin, but still the same problem, and problem happenned on Windows XP only, if running on windows 7, it doesn't have any problem



Edit: i've just test some more times on windows 7, still the same

I don't understand why you are using a batch file to "crash close" Firefox?
Why not close it normally?

Does it malfunction, if you close it normally?

As long as you keep "crash closing" FF, the Session Manager will "think" FF has crashed, because it hasn't closed normally.

You may be able to disable the Session Manager by changing the "When Firefox starts:" option to "Show my home page" or "Show a blank page".
( Firefox button > Options > Options > General )

I use a VB script to start FF and when I close FF (using the "Close" button) the script runs CCleaner for me.

Your steps are indeed useful and clear, lehnerus2000. Thanks for posting this tip.

Thanks EnglishConsult.

Great tutorial except I think I discovered an error in it.

I was following this tutorial for creating a FF Safe Mode shortcut to my FF v33.1 running with my Win7 x64 Ultimate. It didn't work.
I had successfully created one in other PC in 2011 with FF v3.** using the Firefox Support • mozillaZine Forums . All FF updates have worked with it since. This tutorial is dated 2012 and was the latest I could find but I posted a new one at Mozillazine, where I figured out the issue.

I now see what's wrong. The screenshot shows the entry in the duplicate shortcut Target to NOT be in quotes. I don't know if in 2012 it didn't have quotes but if it did it seems the screenshot would show them. Anyways, in the Target, I added a space and -safe-mode and removed the end quote to follow the tutorial instructions and screenshot and it wouldn't work. I later noticed the problem was that both beginning and end quotes need to be there, then add a space followed by -safe-mode. It now works fine.

I hope this helps if someone has the same problem.
