About this extension
Adblock Undetector is a simple tool that automatically blocks adblock detectors on websites. It gets rid of annoying popups and overlays, so you can browse smoothly.

Here’s how it works: it blocks network requests to detection domains like Admiral and Playtime VRM. It also tricks detection scripts on the page into thinking ads are loading. When those overlay popups appear, it instantly removes them with smart, text-based tech that supports many languages like English, Polish, German, French, Spanish, Italian, and Portuguese.

It runs quietly in the background without slowing things down. There's nothing to set up. Plus, there's a toolbar button so you can turn it on or off instantly.

Your privacy is safe. It doesn’t collect any personal info. All settings stay on your computer using Firefox’s storage. No info ever goes to outside servers. Just install it, and you're good to go. Enjoy browsing without interruptions.
