Recently, all of my Google Chrome extensions have stopped working on all of my computers. I want to know if it's possible to reset all of the Chrome extension settings to the defaults (because I'm hoping that this will fix the problem.) Is it possible to reset all extension settings to the defaults?

  • I would try to re-install them, I'm not sure restoring their settings back to default would fix the problem. – amiregelz Jul 19 '12 at 18:55
  • In what way do they no longer work? It sounds more like a browser-wide problem than extension-specific. – Synetech Jul 19 '12 at 19:02

Yes, but it depends on how they store their settings—there are (too?) many.


If the extension stores its settings in a cookie, then you will need to find and delete the relevant cookies from chrome://chrome/settings/cookies (you can delete all cookies with chrome://chrome/settings/clearBrowserData if you don't use them in general).

Local Storage

If the extension stores its settings in local-storage, then you will need to navigate to the Local Storage directory in your UserData folder and delete the relevant data. For example:

%userprofile%\AppData\Local\Google\Chrome\User Data\Default\Local Storage

If you only want to reset some extensions, you can cross-reference the filenames with the extension(s) in question by selecting the Developer mode option in the chrome://extensions to see the GUID (e.g., mgijmajocgfcbeboacabfgobmjgjcoja = Google Dictionary, so delete chrome-extension_mgijmajocgfcbeboacabfgobmjgjcoja_0.localstorage)


Extensions can also store their data in the Databases directory:

%userprofile%\AppData\Local\Google\Chrome\User Data\Default\Databases

Again, delete the relevant folder(s).


Finally, restart Chrome and the extension(s) should be reset to their default settings. Depending on the extension(s), they may or may not pop up their configuration page and ask you to configure them for the "first time".
