What is Firefox if not weak opposition? Even given a reliable firehose of income from Google they haven't cracked that 0.1% market cap, and I don't see how funneling more resources into a browser that's been floundering for over a decade now will change anything.

Ladybird is still a good few years away from being a serious competitor, but nonetheless it is the most viable candidate in the absence of a path for Firefox to become competitive.
