Sorry for delayed response, due to holidays period. Firefox still crashes continuously, I have some chances to run it only using PortableApp edition.

I'm unable to disable Apex Trend Micro and/or SentinelOne, because I'm on a company laptop and this security programs are required by company policy. SentinelOne support says that is a "Firefox's fault" that has a dangerous behaviour.

The crash reports mention qipcap64.dll and this file is part of Websense Endpoint business security software, so you need to check this software

• Firefox 79.0 Crash Report [@ qipcap64.dll ]

Websense claims to only support Firefox ESR versions.

You are right: Firefox ESR works!

Hoping that company will dismiss Forcepoint/Websense DLP in the near future.

Thank you very much.
