How to uninstall this Google Chrome extension?

I have installed Chrome Lock:

However it keeps crashing all the time.

I wanted to uninstall it, but to my surprise, it is not listed in the Chrome Extensions [chrome://extensions/] page.

What should I do to fix this (remove Chrome Lock)?

Solution 1:

If your extensions are not listed, they can be uninstalled by deleting them. This can be done by finding out where your extensions are installed in your computer. You can find these from your Chrome profile or you can search them manually in your Documents and Settings folder.
