I think i've only ever used Firefox since i got the internet (2009), but that also makes my reccomendation kinda moot because i haven't used any other browser. How can i say that Firefox is better than Chrome if i've never used Chrome?

Another side effect is that i'm well aware of all the issues Firefox has, since it's all i've ever used, all the browser issues i've had were in Firefox.

I never used chrome

Chrome is everywhere and everything is built on it or optimized for it.

I wish FF would natively support text replacement in macOS. This shouldn’t need an extension to accomplish a pretty basic thing.

If you need a Chrome-like or Chromium based browser you can always try the various other versions of Chrome out there. Just about every browser that isn't FF is based on Chromium now.
