Hardly. Hundreds of millions of "normies" want a browser that just "gets rid of ads and spam and stuff". If ff can be that go-to browser, they have hundreds of millions of potential users.
Telling Firefox to not to move and get out of the place where it currently is a great contradiction in itself.
Many potential Chrome users were not users, and now they are. You can change public opinion by putting your money where your mouth is, and being persistent about it.
Also, let's not forget that Firefox is kinda preventing itself being detected via standard mechanisms so global analytics show its numbers a bit low than the reality, as well.
Unless we meet in another thread, merry Christmas and happy new year in advance.
