Adblock is an adblocking extension for Google Chrome (and other Chromium browsers) and Mozilla Firefox that can effectively speed up your browsing as it removes ads from website pages.

In the case of some websites, they use anti-adblocking scripts that detect Adblock (and other ad blockers). This doesn’t allow you to use the extension as it was intended.

Those websites will display messages requesting that you whitelist them to unblock their ads, and for this reason, it is very important to know how to make your adblocker undetectable.

In today’s guide we will explore the best options to use in this case, so make sure that you’ll read through it.
