This simple Chrome extension toggles a 'Works on my Machine!' badge on any web page.
Ever had the frustration of trying to reproduce a user error only to figure out it works perfectly on your machine? This extension is made for you! Quickly show your boss that it's probably the user's own fault or something the sysadmin screwed up. Or maybe it's cache. It's always cache. This was inspired by Coding Horror's brilliant idea (https://blog.codinghorror.com/the-works-on-my-machine-certification-program/) and it uses the same graphics (everything used here is licensed under Creative Commons).
