There is a Firefox plugin which I believe is called CleanURLs.
it's interesting that you mention the shorturls OP... I'm almost positive as of today that those links you can share that are like amazon.com/a/ab3cd4 are customized tracking links.
Problem is, if you paste it in your browser from the app, it doesn't go back to the original URL. You have to search the product again and customize the color, number, etc, and then strip tracking again from the url.
Most people just want to send a friend a link of the thing they think they'll like.
Quick someone post that 3rd party YouTube interface for Android. Preferably on F-Roids. I need it.
This is the Internet so let's settle this quickly and efficiently.
