I will go further and say that people hate on Firefox because they care.

We don't see many people here hating on Edge for instance, they may hate the fact that it always wants to force itself in, but not the browser itself. And that's simply because they don't use it, they don't even bother trying, they don't know what to hate about it and they don't care. Occasionally, some people say it is actually good, they get ignored.

Compared to this, hate is a good thing.
