Porting the chrome extension to firefox as a webextension
Firefox Recently added support for WebExtensions which uses the same format as the Chrome Extension so we could maybe drop the firefox only version and just use the same chrome files.
It would be great if someone could build the chrome version and try to load it in Firefox.
