This is an issue with Chrome rather than AdBlock. To fix it, you'll need to reinstall Chrome.

Warning: Uninstalling Chrome this way will completely erase your bookmarks, saved passwords, extensions, and Chrome settings on your computer. Before you proceed, be sure to sign in to Chrome and turn on Chrome sync. That way, all your bookmarks, saved passwords, and extensions will be restored when you sign in to the new installation of Chrome. The only thing you'll need to do yourself is return Chrome's settings to the way they were.

Note: You will need to use an administrator account, have administrator access on your account, or know an administrator password on your computer to perform the following steps.


  1. Uninstall Chrome.
  2. Show hidden files and folders. Be sure to also disable (untick) Hide protected operating system files (Recommended).
  3. Open Explorer and navigate to the following folder:
    Windows 10, 8, 7, Vista: C:\Users\<YourUserName>\AppData\Local\Google

    Windows XP: 
    C:\Documents and Settings\<YourUserName>\Local Settings\Application Data\Google
  4. Delete the Chrome folder.
  5. Navigate to C:\Program Files\Google and delete the Chrome folder there, too.
  6. Reinstall Chrome.
  7. Reinstall AdBlock.


  1. Uninstall Chrome.
  2. Open Finder, go to Library/Application Support/Google, and delete the Chrome folder.
  3. Empty the Trash.
  4. Reinstall Chrome.
  5. Reinstall AdBlock.
