Second, Google actually were caught on making their resources work worse on firefox and other competitors with some hacks.

E.g. https://www.zdnet.com/article/former-mozilla-exec-google-has...

Assuming that literally everyone use gmail, youtube, etc - it had looked that mozilla doesn't work reliably for end users.

There were also a ton of innovations that caused real quality of life improvements that it took firefox an incredibly long time to catch up to, like process isolation preventing a single misbehaving tab from crashing your entire session.

I have always liked Mozilla though so kept trying builds over time, eventually leading up to Quantum the nightlies became better and better and it was easy to switch back at that point.

What a shame it happened in the first place though.

You could still have a million tabs open, something chrome struggled with, so it kept some users.

But it took quantum to get users back.

For the average person it was so much faster than ie 6,7,8,9 and google pushed it everywhere.

It comes default on android helps.
