I am now unable to edit my website after almost a year, I keep getting a message saying "cannot load this site, redirecting" help, so angry

Hi - thank you for your kind reply, yes I eventually tried it on Edge and it worked, my problem was that all of my passwords etc were on Firefox and to be honest I panicked a bit because I am getting on a bit and didn’t remember what to do while trying to speak to the girl who was trying to tell me to try this and that, it still doesn’t work on firefox even after clearing the cache and checking I have the latest version of Firefox
