firefox implemented chrome's extensions format

you should be basically just upload the same code to firefox store

I'll need to polyfill the WebExtension API and use that instead of the chrome namespace.

But yeah, I think it should be pretty simple to port over.

I'm quite busy with other stuff at the moment and don't really use Firefox for GitHub so this isn't a priority for me.

I'd happily accept a pull request though.

Anyone interested in doing this, take a look at this project for a cross platform WebExtension: https://github.com/lukechilds/coinflict-of-interest
