My two cents: Yes, it’s bad. The biggest hurdle to people not “intimately familiar” with their distro is A) what it’s using for DNS configuration and B) realizing that there are so many different ways in different distributions, and sometimes within one distribution, that you have to be very careful what googled results you follow. That many browsers do their own thing doesn’t help. I think the best way to solve it would be some desktop level abstraction like PackageKit where it doesn’t really matter what services does the resolving under the hood.
Don’t bother, that’s normal /sssssssssssssssssssssssssssssss
