[feat] Firefox Extension Support

I'm sure this is already on your roadmap, but didn't see any feature request for visibility/tracking. Keep up the great work!

@kn0wmad Is this for the browser extension or the web wallet? The web wallet should work fine, just tested it in FireDragon, and the extension is only needed for minting UDAs on the marketplace for now. I also would prefer to just add the capability do a sort of OAuth-style redirect so the web wallet can always be used with the marketplace.

Edited title to reflect extension support. Great to hear that there isn't much in the way of limitations for the web wallet though.

@josediegorobles Do you think you can take care of this for us?
