Hola, recomiendo una gran apps en esta ocasión, por su eficacia, por su manera de trabajar que pasa de manera desapercibida, pero.. que hace un trabajo fenomenal, yo recomiendo esta gran aplicación. Indispensable

Excellent and it's also advised by Riseup Labs (Riseup.net).

Contrary to some comments left today and previous days, on my FF 57 eBay works like a charm. However, even if some webpage misbehave, uBO buttons allow to quickly deactivate each single blocker or the whole blocker.

At today's date could not find a better blocker.

Does a good job

Good

This software is quite simply brilliant. It is so invaluable that it is the first thing I install after I have finished a clean install of an OS.

It's one of those things that once you've used it you'll wonder how anyone else manages. Not being able to use it - e.g. on other people's computers, unsupported devices, etc - will feel like some kind of archaic torture.

Utterly brilliant.

Fantastic little adblocker that does what it says on the tin, making my Firefox feel snappy and lightweight again, yay!

Have been using Adblock Plus for some time before which finally slowed Firefox down to a crawl, eating away big chunks of memory and cpu ressources. Was once a fine adblocker but now a useless piece of crap owned by the advertising industry! Even disabling the so called whitelist had no effect, surprise, surprise, when advertisers pay to slip through under the radar.
