I've been using Firefox for several months and have no regrets. On Ubuntu Chrome was doing all sorts of weird things, plus being slow. Firefox's tab groups is also a great feature.

Chrome works fine on the vast majority of Linux distros. Even if a page hangs, Chrome doesn't crash...
I'm not saying there's no problem, I'm just offering my experience to demonstrate that perhaps the problem isn't just "Chrome runs poorly on Linux Mint", and to offer a counterexample to "Linux Mint is a buggy mess".
