Twitembed

Extension that replaces sharing links through the "Copy Link" Button on Twitter with "Copy Embed", which links to the user's chosen redirect domain, (fxtwitter, vxtwitter, fixupx, etc.) improving ease-of-use while sharing on platforms such as Discord. Also includes a hotkey (ctrl+c) to embed while focused on a tweet.

This extension is a fork of the "vx-twitter" extension found here: https://addons.mozilla.org/en-GB/firefox/addon/vx-twitter/
This was done due to recent changes in Twitter's structure causing that add-on to cease functionality.
