Diễn đàn hỗ trợ Firefox

I use Firefox as my browser and used to be able to go a web site or to a link from an instructor and when I clicked on the link or entered the class I was attending, the Zoom meeting would automatically open. That doesn't work anymore. I have to "join via browser but I don't have the meeting id. Why has this become so difficult? Zoom denies being the problem so now I wonder if it's the browser.

Starting yesterday firefox, no recent updates etc, gives a 403 error for several large corporate sites and 404 page not found for most paypal payment pages. These sites/pages work fine with Chrome. There were no changes by by myself to my firefox installation, not any antivirus changes.

Within the last hour today everything is working properly. What is going on? jn
