I'm not sure if I'm agreeing or disagreeing or just providing context, but for me personally it's not about being attached to a particular browser, rather it's about being repulsed by most of them. Edge is user-hostile spyware, Chrome is approximately the same but Google flavored and very very marginally better, I don't trust most Firefox forks to stay on top of security issues, and I don't use a Mac. The result is that my only options really are Firefox, or maybe some of the lesser WebKit browsers. And even then... I'm writing this comment in Firefox, but I don't even particularly like it, it just sucks less than the alternatives.
