What is the best browser for somebody who hates modern browser configurations and doesn't really use social media? Just need a fairly barebones browser without any superfluous gimmicks.

I refused to update Firefox for a very long time but noways you can barely use any site properly anymore without having a modern version installed. So I am pretty much forced to update. Should I bother with a different version of Firefox or switch browsers altogether? I hate the newer versions of Firefox but every other browser seems even worse.
