for a firefox addon I built. The site is at http://previewlink.org, little bit of information here. It's basically a small addon that converts any url-shortened links (such as tinyurl, urltea, snipurl) to link back to this site, and gets the destination url for you. It's currently in the addon sandbox, which means you can't install it from addons.mozilla.org without an account. There's still a direct link on the site (http://previewlink.org/previewlink.xpi) though which should work. All feedback would be greatly appreciated either in comments on the site, email (hi {at} previewlink.org) or on the Tangler forum (no matter how bad). It'll help it get promoted from the sandbox into the public site. Thanks
