Why is Firefox considered bad now? Is Mozilla any worse than Google?

Nope. Not even in the same ballpark.

I don't think Ladybird is ready yet and Chromium has taken itself out of the running with manifest v3. Ie. what do you suggest that isn't Chromium or Firefox based?

chrome works fine for me! have you tried restarting your computer?

Chome is Chromium based and therefore V3 as well.

yes, and it works fine as a browser.

How am I supposed to live without rr
