Whoops! We used a new build tool from Microsoft and didn't discover the new tool had introduced a bug until the build was already in the Edge extensions store. We released a fix immediately, which installs without issue. However, the old build then became a sort of "zombie." Here's how to remove it.

  1. Close Edge.
  2. Open regedit. (Quick tip: Type regedit in the Windows 10 Search bar, then select it in the search results.)
  3. When you're prompted to allow the app to make changes to the device, click Yes.
  4. Navigate to [HKEY_CLASSES_ROOT\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppContainer\Storage\microsoft.microsoftedge_8wekyb3d8bbwe\MicrosoftEdge\ExtensionsStore\datastore\Config\10_BetaFishAdBlock_c1wakc4j0nefm].
  5. Right-click 10_BetaFishAdBlock_c1wakc4j0nefm and select Delete.
  6. Click Yes to confirm.
  7. Restart your computer. 
  8. Open Edge. You should get a notification saying an extension was cleaned up.
