All of a sudden, I get the message below from Firefox. My Safari, Chrome, etc connect fine but not Firefox. I have uninstalled and reinstalled, checked connections, etc. Still cannot get to work. Current version of MAC is macCatalina ver 10.15.5 (most recent update)


Unable to find the proxy server

Firefox is configured to use a proxy server that can’t be found.

   Check the proxy settings to make sure that they are correct.
   Check to make sure your computer has a working network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

You can check the connection settings.

   Firefox > Preferences > Advanced > Network : Connection > Settings
   Advanced panel - Accessibility, browsing, network, updates, and other advanced settings in Firefox 

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

See "Firefox connection settings":

  Firefox can't load websites but other browsers can
