Firefox not loading pages - TLS problem?

Is anyone else having problems with Firefox suddenly not loading pages?

 

Two evenings ago (March 8) Firefox suddenly started not loading pages about 80% of the time on all three of our PCs.I've noticed TLS messages in the lower left corner where Firefox displays the URLs it is loading that I never noticed before.

 

All three of our PCs are configured the same and we changed nothing on any of them before this started other than routine anti-virus and anti-malware updates. Visits to support forums for those products don't have any reports of problems like this.

 

We are in Baltimore County, MD.

 

Thanks for any input.

I'm not having this issue.  I can load pages normally in Firefox.  Did you try clearing history/cache?

I am having this issue with tv.xfinity.com. Seems like it has to do with IPv6, but haven't heard a fix other than disabling IPv6.

It appears this was a problem caused by an update to Malwarebytes Anti-Exploit that was released on or around March 8.

 

Uninstalling MBAE fixes the problem.
