HI, I have a Mac with El Capitan OS and Firefox 78.15.0esr. Recently I can´t open some websites: ChatGPT, Likendin, TunnelBear, Wester Union, etc. Before everything was working perfect. Please HELP! Thanks friends :) When I try to open this website, nothing happens, nor an error, sometimes in certain website it keeps retrieving and thats it.

Many thanks,

Ibhave trie looking for a solution but can't find anythjing that helps me out. I have also changed the password just in case it was that but it wasn't. Any advise on this thanks. Would ghate to go back to Safari. I am using Apple M3 MacOs 13.5. Thanks Anna
