I installed update 2021.04.1 for Waterfox Classic (I am using for EMail). After that I cannot access my Email which uses SSL protection through port 2096 (https). I get following error message: "This address is restricted This address uses a network port which is normally used for purposes other than Web browsing. Waterfox has canceled the request for your protection." I browsed to the following page: https://support.mozilla.org/en-US/questions/1083282 for help and changed according to that my settings of Waterfox (allowed the port 2096). However nothing changed. I cannot still access the EMail domain. Strange is that every other browsers work OK including FireFox.
