Librewolf rocks. I don't know how many more signs people need that this is the browser they should be using nowadays. The default settings are aggressive, but you can relax them if that bothers you. There's a reason they're the default though.
Start getting used to the new future where all your social media and ecommerce shit is going to be pretty broken if you don't let it abuse you and spy on you. Either decide not to use shitty spyware websites and find alternatives, or learn how to make them work anyway. There usually are ways to make them work, and if you can't, alternatives do exist, contrary to popular belief (in fact you're on one right now) they just aren't quite as complete a replacement as what we've gotten used to having at our fingertips. There's more work involved. You have to be willing to make sacrifices and compromises. That's the reality that the tech giants are forcing us to accept. The things they were giving away were never free, they came with the price tag of increasing amounts of your privacy. Now that the price is getting too high for anyone to bear, the free lunch is over, and we need to go back to making our own communities outside the tech giants control.
