I cannot get screen share, webcam share, microphone share to work with my default profile. I get a Cross Origin Request Blocked. If I create a new profile everything works as it should even if I install all the same plugins. I have tried changing security..cross_origin in about:config and it makes no difference. I have a lot of tab groups and sorting in my default profile, so I'd prefer not to have to set that up in a new profile. Importing to a new profile ends me up with the same issue as above. This error is profile specific and I am wondering if anyone knows the specific profile files that I could regenerate, delete or replace to tackle this cross origin blocking. Also I've disabled all my plugins, and enhanced tracking protection on the default profile and it still does not work.. Thanks.
