Popular AdBlocker UBlock Origin has been unlisted from the Microsoft Ad-Ons Store. The extension was earlier available for both Microsoft Edge and the new Chromium-based Edge but has gone missing from the store.
The good news that the extension is just unlisted from the list of extensions available on the Ad-Ons website and is still available on the Store. If you’re using the new Chromium-based Edge then the easy way to install back the extension is to get it from the Chrome Web Store. Another way to get the extension is to visit the extension page directly and click on Get to install the extension. The extension developer Nick Rolls has acknowledged the issue and has reached out to Microsoft in order to get the issue fixed.
