About this extension

Prevents YouTube page, HTML5 player, and Flash player from displaying ads and banners

Read the publisher’s full description

YouTube Player AdBlocker prevents YouTube from displaying advertisements during video streaming. It prevents all types of ads. Please note that this is not a general AdBlocker. It only prevent the "player" from displaying ads. There is no network monitor in this extension and hence it is really light-weight compared to a general purpose AdBlocker. It is useful if you are on a machine without too many resources.
