Disable Crash Recovery Restore Session Option On Firefox

Situation:
When you develop in Flex.. Flash player debugger might freeze Firefox. In particular this is happening in Flex4 then you Debug and accidentally press the Run button while you Debug.

Problem:
When you reload the Firefox, maybe it will try to restore all previous pages without asking. If at your last crash you have loaded several times the application you develop, it is almost fact you are going for new crash. How may we avoid this auto restore session?

 Solution:

1. Open Firefox
2. Type: about:config in address bar
3. Search for browser.sessionstore.resume_from_crash in the list (use the Filter field)
4. double click on that field and set that to false

enjoy your new crashes...
