the custom search engines and the banning of dissenter extension is why i am still on chrome. ff failed me on technical and personal level with these. at least with chrome/google ... the devil you know.
Your answer to ff refusing to host an extension and forcing you to sideload it is to move to a platform that has continuous and proven censorship and surveillance track record? Doesn't make much sense to me.
Chrome has continuous and proven censorship? I think they are more or less on the same page than Firefox: they have their curated "app store" and they inconvenience you if you try to bypass it.
I would use Firefox if they actually were more open and free than Chrome. But if they are the same, just slower, then why would I want to support Mozilla?
