Follow up: Firefox freezes if I click Properties, period!

From Menu Bar Bookmarks, from right click menu, ....

I have rebooted the PC and it still happens. Was working fine yesterday. Any suggestions?

Further follow up: Disabled all add-on, still happens. Bring up Firefox in safe mode (Hold Shift and click short cut) and it does not happen, the Properties window comes up as it should.

Am I looking at a reinstall?

Create a new profile as a test to check if your current profile is causing the problems.

See:

• Basic Troubleshooting: Make a new profile

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins"

If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)
