It isn't competitive. They are paid by Google.

Worse, it's ridden with spyware, and is merely a honeypot for security-aware people that are not sufficiently paranoid to check any of the claims. Like, those VPNs from YT ads that use your IP to give AI companies residential proxies, the same kind of scam.

Spin up Wireshark and take a look at activity of Firefox. Try to shut the browser up. It won't work.

Even if they weren't a Google's proxy company, they would lose to standards commitees being infested by Google, and would have to play the "best luck catching up" game by constantly supporting new versions of JS, APIs and CSS features that nobody needs (except Google's YouTube will use them to stop you from using an adblocker).

FF is governed by ex-Oracle managers at the moment, singing the Google's song. Don't anthropomorphize your lawnmower.
