According to internal tests ran by our developers, Ghostery ad blocker prevents you from seeing ads on YouTube to a safe 99%. If you find the one percent where an ad slips through the filters and magical cosmetics of the best ad blocker at Ghostery, please drop us a line with the example at support@ghostery.com. It will help us to cover it as well.
Ghostery ad blocker works by leveraging the effort put into open source block lists, maintained by the amazing community of developers worldwide dedicated to privacy online.
This can happen for mainly two reasons:
If you get ads served by YouTube on a regular basis, please check your personal settings of the Ghostery Browser Extension - maybe they are misconfigured by mistake.
If the above two screens did not help, go one step deeper into your Ghostery Settings and check if you trusted the site youtube.com mistakenly. For the Ghostery Ad-Blocker to block ads as desired, you should not trust the site youtube.com.
For the Ghostery Ad-blocker to work as intended on youtube.com, the settings need to look as on the screens below:
Make sure the Ghostery Ad-Blocker is enabled in your Ghostery Browser Extension settings and set up for blocking ads on youtube.com. For any question, drop us a line at support@ghostery.com.
