======================

I have copied the above report but can not add further

I see you read the first part of my earlier post. Now please read the second part.

This is a shutdown hang where Firefox takes too much time to close and a crash is forced.

• bp-b1809d08-8c40-47ec-8769-b2d8d0180911
• Firefox 62.0 Crash Report [@ IPCError-browser | ShutDownKill ]

Such shutdown crashes can have a lot of causes and there is usually not much to tell about.

You can create a new profile to test if your current profile is causing the problem.

See "Creating a profile":

• https://support.mozilla.org/en-US/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.
