I've created several extensions/scripts to enhance one's experience on paizo.com:
Newest Extensions (Working circa May 2013)
Truesight Goggles (Mozilla Firefox Only)
Newer Extensions (Working circa Dec 2012)
Older Extensions (May or May Not work as intended)
Gargamel (Remove Smurf Avatars)
Play-by-Post Character Info Popup
All extensions/scripts (except Truesight Goggles) work with Google Chrome and Mozilla Firefox.
Chrome users must download the extension/script and drag-and-drop the file into the Extensions page.
Firefox users must install the Greasemonkey Plug-In in order to use the extension/script.
