While I think the anger surrounding this is slightly overstated, is there any Desktop fork of Firefox that can essentially just act as a "we prevent Mozilla from doing anything harmful to it's users", while compromising on as little functionality as possible? There's only so many stories of Mozilla deliberately trying to reduce it's browser market share to zero you can put up with before you start looking elsewhere.
I'm thinking something in the same vein as Iceraven, which is a fork of the Android version of Firefox that aims to make the browser more usable for humans instead of servicing the overly restrictive mobile environment/tracking that's bog-standard in most mobile platforms.
I considered Librewolf, but it's willingness to break pages in the name of excessive anti-fingerprinting (the RFP mode breaks a lot of interactables) and ideology (blocking DRM) makes it kind of unacceptable for this purpose. I guess I'm not looking for a privacy fork, just a fork that protects me as a user from anti-features (with widevine in specific not being an anti-feature; I don't like widevine either, but it's kind of necessary for using a browser these days.)
