Diễn đàn hỗ trợ Firefox

I've tried everything under the sun that I've seen other people suggest for this problem like custom scripts and altering the config but no matter what I do Youtube just doesn't load videos AT ALL any other video streaming site works wonderfully like Netflix and Youtube works on explorer just fine if anyone has a solution or even just an explanation as to why this is even happening it would be greatly appreciated.

For quite some time (months), the Alarm.com web page has not worked properly. I get the message "Oops...Something went wrong.

Don't worry your system is fine; it's just an internet thing."

Refresh does NOT solve the problem. Today I resorted to using Edge, and all worked well. It's clearly a Firefox problem. Can you tell me what's going on? Is there a fix? I'm disappointed that Firefox can't deal with a web page.
