Attachment: Firefox's error page

I used my laptop in a new location and while not being connected to a WiFi, I noticed that Chrome and Safari inform the user of the actual problem (No internet) while Firefox's error page says its unable to reach the page with options to try for the user.
If Firefox can provide more definitive root cause to the user, it will be more user-friendly, convenient and help the user fix the problem sooner. This is one of those scenarios.
For comparison, Chrome shows the text "No internet" and Safari says "You are not connected to the internet". I'll attach screenshots from both to this bug.
P.S. did you know that Chrome's no internet error page also has a dino game easter egg? https://thelinuxcode.com/how-to-play-the-no-internet-google-chrome-dinosaur-game-both-online-and-offline/

Thanks, Neha! I think the easter egg is fun! Jeff Pfaller and I looked at error pages last year and did a bit of a look & tone refresh, here's a link to the designs https://www.figma.com/design/yawrXicozZQ2zvLYsjdQBb/Error-Pages?node-id=3871-32898&t=b327LHs0xYmJAFTk-4
