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

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.

Was working great, but now it takes LITERALLY ONE HOUR for me to switch tabs, or to open anything. Firefox posts a notice saying that a "long running script from AdGuard is preventing this page from displaying." I turn off AdGuard and INSTANTLY the page displays. I have left for an hour and came back and the page was still NOT loaded, and this is happening 100% of the time. No more AdGuard for me... (I gave them MONTHS to straighten this out... I shouldn't have given it a second thought and removed it on the first glitch...)

it will not download-crap

add in google search results his own ads. I thought i had a virus but deactivated this addon and there are no more ads in search results

is recognized as ad-blocker and so blocked by sites like:

Nie da się zainstalować, podobnie jak wszystkie pozostałe blokery!!!

No permite desinstalar este complemento y se aferra al inicio de Firefox impidiendo que se conecte a internet. Al escanear en busca de virus, esta extensión me ha descargado addware y virus.

I'm a royal and paid user of Adguard. I love its firefox extension it works like a charm!

BUT, I would like the team explain why you need so many permissons? It really matters.
