NoCoffee: Visual Impairment Simulator

Four years ago, on a snowy February day, Aaron Leventhal huddled in his unheated home and created a Chrome extension called NoCoffee. This extension allows users to experience web content through different lenses of visual impairments*.

I recently ran across this extension again, and thought it is high-time we ported it to Firefox. Firefox’s support of WebExtension standards means that this should be trivial. It was! With Aaron’s permission, I posted the source to github and did some tweaking and cleanup.

You can now try out the extension in Firefox!
