Hi

Do you have an example of one of those websites that we can try here?

What happens when you try to access them? Is there any error message?

I am a college prof and use a learning platform for teaching online class. Up until this morning I had no problem using the learning platform through Firefox. Today, I access the learning platform but the courses I teach do not load. All I get is a buffering circle. I have to use a different browser to access my courses without any issue.
