Have just updated to Firefox 40.0, but when trying to open, continually crashes. Tried creating a new profile according to instructions, but it is not possible -- keep getting a crash report, and can neither create a profile, delete an existing one, or rename it.

There have been crashes caused by Trusteer Rapport reported.

Make sure that you have the latest updates of your Trusteer software. You can try to contact Trusteer for support.

Try to update or uninstall and reinstall Trusteer Rapport and if that doesn't help then disable/stop the program for now.

  • Mac:System Preferences -> Other -> Rapport -> Stop Rapport

If you have submitted crash reports then please post the IDs of one or more recent crash reports that start with "bp-":

  • bp-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

You can find the report ID of recent crash reports on the "Help > Troubleshooting Information" page (about:support).

  • Click the "All Crash Reports" button on this page to open the about:crashes page and see all crash reports.

Alternatively you can open about:crashes via the location/address bar.
