I was using Mozilla Firefox Version 96.0 (64 bit), on 1/13/2022 at around 2:30 am EST to both watch Netflix while getting account balance information and transferring funds through the website of one of my financial institutions - and the browser become completely nonresponsive. Not a single website will load in the browser. If I use any other web browser, I can access the websites without a problem.

I ran updates to Mozilla and Windows earlier in the day - but nothing to my knowledge was updated or changed after I had logged into and was successfully using netflix and my financial institution website.
