|Ok, you can create a new link on you desktop, for "firefox safe mode".|
Simply create a normal new link on the desktop for your firefox.
When done, rightclick on the link and choose properties.
Add -safe-mode to the line so that it looks like:
"C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode
Click ok and try to start that firefox in safe mode.
Please send a reply, if you solved the problem !!!
