Google-chrome – Google Chrome missing extensions icons / reinstall extensions

You don't even need an extension. Just go to Chrome preferences and click "Personal Stuff" and choose "Set Up Sync..." Then enter your Google account information. Repeat this for all the computers you want synchronized. This will sync everything, passwords, extensions, bookmarks, etc. When setting up the sync, you can also specify what to sync if you only want extensions.

Do you have your extensions set to sync to a Google account?

I have the same version and I have been having a similar problem with all my extension settings being reset every time I do a clean launch of Chrome. Here is a temporary fix that worked for me:

1. Open your Settings by using the menu item Tools => Setting or browsing to chrome://settings/
2. Click the "Advanced sync settings..." button under "Sign in"
3. Change "Sync everything" to "Choose what to sync"
4. Uncheck Extensions
5. Click Ok
6. Close every instance of Chrome and do a clean launch (or just reboot your computer to be safe)

Of course, this is only a temporary fix because it makes all your extension settings local to that computer, but for me that is better that reapplying all my extension settings every time I launch Chrome.
