We have just finished version 0.83 of Power Twitter, a plugin for Firefox web browser that greatly enhances twitter.

Twitter pages now include:

• Photo sharing with embedded flickr photos
• Video sharing with embedded youtube videos
• Shared tinyurls are unwound so you know where they link to
• All links are mapped to their web page titles
• Additional user information is mapped to twitter users thanks to data conduits via 30 Boxes (e.g. flickr accounts, blog posts, del.icio.us links, and tons of other social media!)

and then drop it on Firefox to install it. Restart your browser and try this test page.
