Best!

Easily the best adblocker. I cannot recommend it enough.

În sfârșit, un blocant eficient. Folosește procesorul și memoria foarte puțin.

Bloquea todo por lo que es una tranquilidad de leer algo en internet o ver algo

A must have. Makes everything cleaner, faster, and safer. The zap/pick features are SO useful for getting rid of site bloat. Not to mention how it's all seamless; there's no big gaps of empty space where ads or other nuisances would be. If I'm on a new computer, this is the extension I ALWAYS get first.
