Really good to block ads on the web AND on Facebook pages. First time it doesn't, but select the ad you want to block and it will no longer be displayed.
So you can choose what to see and what to block.
I installed the Firefox extension and the PC software version.

EDIT : After 1 month, the app indicates evaluation time is off. I can still use the addon but in fact I have more ads in Facebook than I have ever had before using Adguard.
So I have removed it from my computer and come back to free addons.

Ad guard worked perfectly, blocking all adds and pop up when clicking on a link, and boom all of a sudden 100 pages open up with ads

So far the best adblocker that I've found. Until recently was exclusive to Firefox but now I can see it is available on more platforms and it is the only one that I've managed to block entirely the ads on outlook mail app and expand the mail content to the end. Other ad blocers just block the ads but the right side stays empty and not usable.

Better to try

ótimo programa, possui filtros excelentes, amei.

The best adblocker I've ever tried! Thanks for your great effort! :)

Лучше, пока, не придумали!

Me gusta mucho, cumple, ralenta un poco el navegador, pero es 10 en seguridad

There is no one way to one-click white list a site like on other adblockers. The filter setup is confusing and demands "importing" instead of just basic URL input. In order to use on a site that requires disabling, you have to completely turn off the entire extension or import a whitelist from a file. That is absolutely ludicrous.

很好用，手机端的也不错~不过存在误杀，会导致一些网页的图片被屏蔽~无伤大雅~
