Here are the latest five of such report Crash IDs: bp-89954b00-9faa-4baa-be0a-e33312150619 bp-c76b662d-b930-4791-b1fe-86b8f2150619 bp-b2f197d8-7258-465a-bebd-33d8d2150619 bp-14c45426-5aba-474f-9bdd-2e48b2150619 bp-9318041b-a520-486a-8e19-4a5992150619

How you geniuses can make anything out from these I find baffling (but admirable!) :)

Try to create a new profile as a test to check if your current profile is causing the problem.

See "Creating a profile":

• https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
• http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

Hi - thanks for the quick response - I'll try that now.

Hmmm the Profile Manager won't start either - it brings up the crash reporter with the following Crash ID: bp-a454ed02-498d-4bc0-b320-d55562150619 bp-332540b1-ed47-40e0-a72c-479032150619 (I tried twice)

Is there another way to create a new profile?

Thanks for all the help. It is now sorted.

By the way, just in case anyone wants to know, I sorted it myself by (re?)installing the latest version. Thankfully it didn't lose all my settings. I felt lucky! Been fine since.
