Firefox was working fine until yesterday. When I tried to access internet I got an error code 1001 and a notice that something called cloudfare was not accessible. It suggested that Firefox was not registered on cloudfare.

MS Edge works fine incidentally, but I prefer Firefox.

It looks like a DNS issue. Try to switch DNS in Firefox to NextDNS or https://dns0.eu

many thanks for your help.
