Earlier, I joined a zoom meeting from a facebook group (facebook in a container). I had Yahoo open on my browser. Now, no matter what I do (including uninstalling and reinstalling firefox), I get the message every time I try to open a link from a particular email to a website totally unaffiliated with facebook. It looks like facebook grabbed onto the open tab and I can't get rid of it. I'm using a different browser to access that url, but I'd like to get facebook out of my yahoo business. It looks like FB is trying to track my activity on the web. Please help. BTW, Yahoo was in a personal container and the url for zoom opened up when I joined the zoom meeting from facebook, so all 3 of those tabs were open for a couple of hours. Thanks for your help.
