Leaning hard into delivering content that you can "trust" would be an interesting direction for Mozilla. I suspect that will put some crosshairs on Mozilla as an organization, though. While that would be good for users, there will be folks who don't like the idea of spotting fake content or doing any labeling of content...
Given their complete reliance on google for funding and biased political stance. I don't think they are in a great position to deliver content you can "trust".
While I do agree to some extent. I think the vast majority of the tech side of Mozilla who work on the products and not the marketing are more concerned about the tech. I only wish they got the bulk of funding, and Mozilla org would cut way back and let the products speak for themselves for a while. If they hadn't spent so much trying to find other funding and revenue streams, they could have had decades of runway to work on improving their software.
