Start Firefox using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

While still in Safe Mode,

In the address box, type about:crashes<enter>. Note: If any reports do not have BP- in front of the numbers/letters, click it to submit them.

The crash report is several pages of data. We need the report numbers to see the whole report.

Using your mouse, mark the most recent 7 - 10 Submitted crash reports, and copy them. Now go to the reply box and paste them in.

Please, Do not post a screenshot ! !

It at first seemed like the problem was gone in safe mode, but it is still happening. I tried to retrieve the crash reports, but the response was that "No crash reports have been submitted."

One page that hangs a lot in safe mode is https://games.washingtonpost.com/games/addiction-solitaire

I also had a "not responding" message in safe mode when I tried to access one of my healthcare sites and washingtonpost.com.

I saw that my last FIrefox software update was 21 January and that is right about the time this problem began to occur.
