Mere "adblockers" let spyware through. But this uBO extension also lets you block spying. To start, set it to "Advanced User" and you'll get to see how spyware from google is just about on every site.

@av307: Decentraleyes doesn't just block the original, it also substitutes the javascript that was blocked. So you don't lose the functionality that the javascript provides. You get an identical copy from Decentraleyes, but nothing from google. So google can't track you.

Whenever google provides any "free and helpful" stuff to you, that's really a spying tracker.

This extension is a must have if you value defending your privacy against BigTech. @SYNZVATO is the "real deal", he is a dedicated privacy advocate - he's not a business that betrays its users in the way that e.g. Brave browser betrays its users to google (look into--> google fonts).

Here is a very meaningful example: when Micro$oft bought github, SYNZVATO left github. This guy deserves more recognition. He is a true pioneer.

I always install this and uBO on every browser. Thank you, Thomas, for expending the effort needed to make this available on Opera.
