From a user privacy perspective there is not much difference between FAANG. They are all competing for user data. They all want to collect and store it in their data centers. The "significant differences" that some users might think they see are likely a reaction to the lack of viable alternatives. There is no FAANG which is not competing for user data. Similarly, there is no major browser that deliberately lacks the feature set necessary to facilitate that data gathering. From a user privacy perspective, the difference between "major browsers", or FAANG, is not as significant as it is portrayed by many commentators. The major similarities far outweigh the minor differences, and I think Mozilla would agree they are not looking to go in a profoundly different direction than Chrome or other major browser. They seek market share and so they will always match the others' feature set. As other comments in this thread elucidate, all these browsers are funded by advertising. As such, we cannot expect the differences to be significant. If the majority of users are not concerned with things like telemetry, search box queries forwarded to Google, auto-loading resources, complexity, etc., then that is the user base to which Mozilla will cater. The small minority of users who find the status quo unacceptable are not important to Mozilla. Mozilla has enough cash they could prepare a separate, stripped-down bare bones browser in addition to Firefox for those few users who really take privacy seriously who want zero data collection by default. They won't. That is why we see a user going through all this effort to "un-Google" Chromium. It would similarly take substantial effort to "un-Mozilla" Firefox. Both Google and Mozilla gather user data by default. They each phone home early and often. The question is how many users would actually be interested in a radically different browser that, by design, made data collection and serving ads much more difficult. Perhaps that number would grow over time as word spread. We will never know. While this could be an experiment of great interest to some privacy-conscious users it is not an experiment of interest to Mozilla, chasing advert-funded "major browser" market share.
