Firefox should release a separate build - "base", "core", "classic" - clearly, I am not a marketing person, but idea behind it, that this is only a browser without any extra features added. No "AI", no studies, no account sync. Only bare minimum browser, that allows user to do their internet things and, if they ever desire, will install all extra bells and whistles as extensions. No need to agree to any EULA either (remember, that it was added to Firefox?). And, the best part, all existing users will still keep using the same old Firefox version, no surprises for them. Now, I assume that someone will tell me, that this version already exists and is called ESR :)
