Yeah… It’s a bit hard to balance things like this though, I’ve seen lot’s of folks complain about how their Firefox is apparently “broken” because it now suddenly has this empty margin around web-content seemingly wasting space for no reason - and then it turns out that they have deliberately turned this very feature on. And that is even if the feature is completely hidden - I wonder how many more complaints there would be if options like this are made more accessible.
Doesn’t really sound like a company that I would want to do any business with then.
