>"No. FF is hopelessly enshittified."
Couldn't disagree with you more. If you want that type of browser, look no further than Edge/Chrome. Rigid config, lack of user control, often mysterious goings-on, etc. That is on top of Google trying to completely take over what is web standards, mostly in favor of their own products and services (and drag all the other browsers with it, since they are now all Chromium, except Firefox and those based on it).
>"The only way to fix it is to strip out all the telemetry/AI/adware"
What little telemetry/AI/adware, if you can call it that, is 100% under user control. Mozilla is completely open about what they do and where, and you can turn all of it off. Nothing is hidden. And it actually is off when you turn it off. And it stays off.
>"and preinstall good adblock."
Mozilla isn't going to put that directly into Firefox. It would be suicide. Yes, we all immediately install a VERY good adblock, which is UBO. And it is the real deal, unlike anything you can put in Chrome or Edge. But that is our doing it. If that were preinstalled, it would make Firefox an enemy of some very powerful corporations. Mozilla has enough issues without adding that.
