Indeed.

It is important to try to avoid letting perfection be the enemy of good.

Firefox is at least something that is distinct from WebKit or Chromium (which is itself based on a fork of WebKit). That's good.

It's not perfect, in part because deals with Google pay for most of it, but it is still good despite its imperfect status.

Which sucks because it's not exactly fantastic as a competitor. There's still very, very noticeable performance differences and render speed/pattern differences that after you've been using a chromium based browser for a long time give firefox a feeling of being slow (it's not, it is absolutely just a perception thing, but it's enough to put you off using it)
