Firefox 8.0 Crash Report [@ DbgBreakPoint ] 

... and related bug

691271 RESOLVED WORKSFORME Crash mainly close to startup in [@ DebugBreak ] [@ DbgBreakPoint ] with Roboform (Fixed in Roboform 7.6.2)

I found this posted to the bug report:

If the robotaskbaricon.exe program is running (i.e. the Roboform icon is in the system tray) and the "Browser Integration" option to "Attach Roboform to Firefox even if Adapter is not installed" is checked, the Beta and Aurora loads will crash on start up whether or not the Roboform Toolbar for Firefox 7.6.1 add-on is installed or not.

Can you update Roboform?

Running Roboform 7.6.6 (latest) and still have crashes when Forefox 8.0.1 attempts to start.

slvmart,

You have posted in a "solved" thread started by lazaruslong, another Firefox user.

You may have a different problem. See the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article and post back with your crash report ID in a new thread, which will then show your own Firefox version, operating system ond other system details.

I'll lock this thread.
