I am running a macmini with MacOS 10.13.6. I downloaded Firefox 93.0. The app will start up, load the urls but cannot access any of the servers. E.g. "We can’t connect to the server at www.cbc.ca." I connected to your site via another browser and followed instructions to add another profile, reinstall Firefox, and restart in trouble shooting mode. The "terminal" tried to send a crash report but could not because of a problem accessing your server. At the same time my Mail accounts are all offline and cannot be put back on line. I am dead in the water, and am using a Windows laptop to read emails. Please help. Alan O'Connor - ... ===================== Firefox screen contents below: Hmm. We’re having trouble finding that site. We can’t connect to the server at www.cbc.ca. If that address is correct, here are three other things you can try: Try again later. Check your network connection. If you are connected but behind a firewall, check that Firefox has permission to access the Web.
