Google Chrome: What to do if a problematic extension crashes Chrome

If after you install an extension, your Chrome can not start and run, you want to run Chrome in a safe mode so that you can disable the extension which causes the problem.

Method 1

Right click on the icon of the Chrome, and select Properties on the context menu. In the Shortcut tab, look for the Target box. Append the argument "--incognito" to it. It will then look like:
        "C:\\...\Google\Chrome\Application\chrome.exe" --incognito

Click OK to accept the change.

Start Chrome.

Click the Tools icon at the top left corner and select Tools|Extensions.

You can uninstall the problematic extension.

Last step, don't forget to go back to the Properties of the Chrome icon to remove the argument "--incognito".

Method 2

The above method will not work if you enable the extension in the incognito mode. If that is the case, you need to manually remove it.

Right click on the icon of the Chrome, and select Properties on the context menu. In the Shortcut tab, look for the "Find Target ..." button.

Click the "Find Target ..." button to go to where Chrome is installed.

Go up a directory and you will see there are two folders: Application and User Data.

Enter User Data/Default/Extensions. All the extensions you have installed are listed here.

If you are not sure of the id of the problematic extension, look for the most recent one by the Date Modified field. Go into it and read the file "manifest.json". There should be a field named "name" in the file.

When you identify the folder of the extension, just delete it.

Start Chrome.

Note: if the extension was loaded as an Unpacked Extension, you don't need to go to the above location. Just go to where you loaded it (where the source code is) and move it away.
