Google-chrome – Is it possible to reset all Google Chrome extension settings

google-chromegoogle-chrome-extensions

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?

Best Answer

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

Cookies

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)

Databases

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).

Post-reset

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".

Chrome – How to open Google Chrome with extensions disabled / turned off

thirtydot is correct, run Chrome with the --disable-extensions command-line option to disable extensions.

Technically, it doesn’t so much disable all the extensions as much as hide them so that Chrome thinks that none are installed, so this won’t help in your particular case. t_b_b, since you cannot disable extensions in-browser and the command-line argument hides all extensions, what you want to do is to manually disable them. Open your User Data folder then open the file Preferences in a text-editor. Now scroll down to the line starting the settings blocks: "settings": { Each of the extensions will have its own block inside the settings block. To disable them, change their states to 0: "state": 1

To simplify things, just do a search for all lines containing

"state": 1

and change them to

"state": 0

Have you tried syncing your chrome to an account, and doing a wipe/fresh install? Perhaps the sync data is bad and it might be good to get a fresh sync going on a new account.

As you stated, the culprit was likely the experimental settings in about:flags which makes sense. Hard to always see the far-reaching impact changes there might have. Odd that it affected all extensions though.
