Firefox: 141.0.3 macOS Sequoia: 15.6 A very odd problem here … I have a bookmark to a website. I click on the bookmark and the website login page comes up. I enter my email and password and click on Login. After a short interval while Firefox seems to be searching, up comes: "Hmm. We’re having trouble finding that site. We can’t connect to the server at en-gb. Did you mean to go to www.en-gb.com/?" (See image) Well I don't want either and it's not what has been submitted. However, I click on the bookmark a second time and the website appears as expected. I've restarted Firefox in Troubleshoot mode - exactly the same behaviour. I've also tried Safari and DuckDuckGo web browsers - exactly the same behaviour.
