TwitEmbed 作成者: Vi Georgeson

Alternate version of "vx-twitter" addon 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.
Add-on that replaces "Share Post" links with links to fxtwitter.com, a well-known redirect used for twitter embeds. And also has a hotkey (ctrl+c) to do it if you're on a tweet's page already.
