- Start accepting small individual donations solely for the Firefox team (rather than generalized Mozilla stuff that goes on anything but Firefox).

- Start crowdfunding for features.

- Go RedHat route, offer an enterprise version with centrally managed profiles and DLP feature. Not exactly free-as-in-freedom stuff but still better than adtech.

- Get some EU bureaucrats thru a FUD session against Chrome (does it counts as FUD if it's true?), then apply for some EU funding program. Dirty and messy, still better than adtech.

None of this is particularly lucrative or clean, but I don't see how AI would bring them any __revenue__ (do not confuse with investment) at all. There are too many players there already and many of them are more established - and what Mozilla have?

- Their engineering team? Maybe.

- The browser engine? Completely irrelevant (and that's exactly the problem).

- Their userbase? The userbase they have left seems extremely averse to value-added features in general, and the AI kind in particular.

Then assume they focus on integrating AI into the browser, how do they monetize it next? Sell data? Then there is no reason to choose them over Google. Charge for interference? No chance to compete against established hyperscalers there and would go against their local-first selling point.

The sad truth about platform-crucial software like a web browser is that monetizing it in any way inherently reduces it's value for users. And in case of Firefox it's a pretty small margin that keeps it competitive.
