I have tried several times to sign on to a tele/health conference with my doctor. I get the message that Firefox does not support this kind of online conference. Since Covid 19, I have had to resort to tele/health conferences for any questions on help I need for a health problem. Is there a way around this? I am very partial to Firefox, but have not been able to use the Firefox browser for the tele/health. Will I be forced to download and use Google Chrome?
