Personally when I bang my toes against a corner, I don't think about removing my feet just to prevent toe banging.

Reductio ad absurdum aside, if I'm experiencing an issue in a browser, my first thought is to diagnose and fix the issue or find an expectable workaround rather than change to a browser with obvious privacy issues.

Currently, you'll see words, phrases, and names like "Firefox sends", "telemetry", "Google", "Microsoft", "share this with our partners", "share that data with its partners", "sends us data", "share aggregated data", "our third-party ad platform Kevel", "AdMarketplace (a third-party referral platform)", "Cloudflare", "Comcast", "Adjust", "Google advertising ID", "our partner Fastly", and so forth.
In my opinion, I wouldn't expect to see any of those in the privacy policy of any software product that truly respects my privacy.
They're literally all Chromium unless you think that Lynx renders websites better than Firefox
