What Adblock Plus does
Adblock Plus blocks ads, pop-unders, and similar content across websites, including YouTube video ads, using filter lists to identify what to remove. It runs automatically once installed, with a toolbar icon for pausing it on individual sites.
Adblock Plus and acceptable ads
By default, Adblock Plus allows a category of ads it labels acceptable to pass through, as part of a program that funds the extension. This setting can be turned off in the extension's options if you want it to block all ads without exception.
Is Adblock Plus safe?
To identify and remove ads, Adblock Plus needs to read and modify the content of pages you visit, which is standard for any ad-blocking extension. It's widely used and maintained, but as with any extension with broad page access, only install it from the official Chrome Web Store listing.
