I've had an issue for a long time where certain websites just won't work properly on Firefox. This issue seems to be specific to this particular configuration of Firefox I have, as the problem doesn't occur on my other MacBook, nor on other browsers, and this problem persists even through upgrading this MacBook from an Intel-based processor to Apple silicon. I've exhausted all of the troubleshooting methods suggested by Mozilla here: https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems. My last hope is that it has something to do with Firefox's browser internals, though I'm not tech-savvy enough to understand what may or may not be working correctly with said internals.
As a few examples of what I mean when I write that certain websites won't "work properly," a reading on Coursera seems to have a scrollbar that can scroll indefinitely without ever actually scrolling the page down for me to read additional text from the article. Certain websites will fail to display certain videos or interactive media. And certain other websites will fail to display anything at all. (I wish I could be more specific in describing these "certain websites," but I can't recall what they are at the moment.)
Let me know if you need any additional information to help diagnose this issue.
I greatly appreciate any time and effort that you may spend trying to help me with this issue!
