I think they went exactly in the wrong direction. Given that they have a very small market share it is understandable.

However, what if the latest Firefox or Chrome would just have a user string "Chrome/80.0 (Windows 10; Win64; x64)"?

And if you run into a problem you get a button that reverts to the old horrible piece of junk.

Now that robots.txt is established and security.txt is almost there, the next thing we need is a contact.txt that browsers can use to offer a button that will allow sending bug reports to webmasters without having to search the site for the contact address.
