The extension's summary says what it is on the tin. I adore the customizability (as in what is blockable, what isn't, even blocking popup tabs and JS for a singular site) and have been using it for months at this point.

Removed the "clear Cache" button. This blocker is now worthless for some streming websites with addblock detection tools. what a shame

I just noticed that the 2 buttons under Filter Caches Clear and Refresh are missing.

An absolute powerhouse of blocking adds and a must for safety these days

Sencillo, con herramientas útiles y eficaz. Ese es uBlock Origin. ⭐⭐⭐⭐⭐

Surprisingly memory lite for such a robust extension. Even using it on a 32-bit system doesn't strain resources in the least.
