Yes but Internet Explorer had massive issue, nowadays it’s Firefox that has compatibility issue, doesn’t have a platform where its default (Microsoft has windows/edge, android/chrome, iPhone/safari) and no meaningfull advantage on the other.

The cards are stacked against it, if only they could use Google money to get some advantage, like a better design. Right now if I open Firefox there is 3 row of sponsored clickbait articles. The reason I paid money for Mac is because I was fed up of the very same bullshit on windows, make something lean, sleek that works well and people might use it but here it’s a kind of dinosaur software that is even filled with sponsored articles.
