American corporations like Facebook, Google, and Amazon make billions from weaponizing your private data. And you don’t even have to be using their products for them to steal from you!
Rob them of that option by blocking ads and trackers.
Starve these bastards of your data, and you’ll kill their revenue.
Note that Ublock and other adblockers work much, much better on Firefox than they do on Chrome and other Chrome based browsers (which is basically all other browsers; Edge, Opera, Brave, etc). This is because Google deliberately crippled adblockers.
