Again, I use Firefox, for the most part because of the reasons you've described. But none of what you've said is really an argument for security or privacy against the browser. If you just wanna say Google = evil, so don't trust anything they make, that's fine. The chromium forks aren't google owned and they don't need respect what google tries to do. Case in point manifest v3 came and brave still has native ad blockers and intend to support both manifest 2 and 3 going forward. It's really just a matter of who has the bandwidth and funding to maintain a browser of the scale of chromium or Firefox. Google clearly does, mozilla does a decent job despite the iffy funding situation actively restricting donations purely for the browser. If its just small privacy enhancing tweaks atop chromium smaller vendors like brave can do that. End of the day chromium is a well optimised, standardised and frankly well written browser that is perfectly fine for anyone that wants to use it. Should Google be the entity in charge of chromium given their clear conflict of interest, obviously not. But no one else has stepped upto the plate and mozilla is clearly the inferior in regards to features or browser optimisations (just due to scale of support available). Don't get me wrong, Firefox is great and everyone should use it for their own sakes, but this just blind fear mongering of anything chromium related isn't productive.
