Firefox Port and Version Increase from 0.4.6 --> 0.4.7

I ported over the extension to firefox and it is working fine. I had to change some things in tippy.min.js. My suggestion is to test on chrome on your side to ensure functionality remains unharmed.

Thanks for this! It looks like you've modified the minified tippy library. Is this just a new version (if so, which?), or did you make other changes to it? Do you have a link to the original source?

I understand that submission to the mozilla add-ons store requires the actual unminified source to be available for review, with correct version numbers and links (https://extensionworkshop.com/documentation/publish/third-party-library-usage/), so I think there are a few further changes necessary (or at least details to be researched) for a number of libraries before I can actually submit this for signing.

I am just now seeing this...I'll double check about the versioning and get back with you this weekend!
