I just downloaded WaterFox, it looks nice.

When they say "AI browsers are proliferating." and "Their lunch is being eaten by AI browsers." what does that mean? What's an "AI Browser", and are they really gaining significant market share? For what?

I found this (1) that suggests that several "AI Browsers" exist, which is "proliferating" in a sense.
