I don’t disagree that Firefox is deliberately gimped, and it’s built in blocking features on desktop match Safari on iOS. I’m not sure I really agree that Apple is a “shady company,” in many respects they are doing a good job with end to end encryption and ensuring that they don’t have access to your data in the first place (not to excuse their extreme walled garden approach, which stifles competition and limits good options like Firefox [real Firefox] with uBlock Origin [or uMatrix]).
