Uninstall manually a Chrome extension

It can sometimes happen that an extension doesn’t want to be uninstalled with the steps provided by Google Chrome Support (to be tried first): https://support.google.com/chrome/answer/113907?hl=en.

Don’t worry, there’s a workaround available to delete definitely and manually this extension. Here are the steps:

  • Type about:extensions in the address bar and click on Developer Mode in the top-right hand corner
  • You will so find a ID line below any extension name. Copy this extension ID in a external text editor for example (you will need it several times later).
  • Right now, close entirely Chrome
  • Open Windows Start Menu and type the following line in the search box (or in the Execute menu):
    %LOCALAPPDATA%\Google\Chrome\User Data\Default\Extensions
  • In the explorer which has just opened, delete the folder with the ID matching the ID you have previously retrieved.
  • With the same steps, now access to this folder:
    %LOCALAPPDATA%\Google\Chrome\User Data\Default\Local Storage
  • In this folder, check if there is a file with a name such like chrome-extension_ID_0.localstorage (replace the ID value with the good one from your extension). If there is, delete it also.
  • Finally, one last step to be sure that this extension won’t re-install by itself automatically, you can check by typing regedit in the search bar of your Start Menu and then find the following path: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\ExtensionInstallForcelist. Check that there is no entry containing the extension ID.
  • If there is, delete it ; else, everything is good !
  • You can now restart Chrome, and everything should run smoothly and fine !

Here it is, the extension doesn’t exist anymore on your PC ! (Don’t worry, you will be able to re-install it later if you want).
