Add Online Videos to Plex Queue using a Chrome Extension!
Instead of using a bookmarklet to send online videos to your Plex queue, this is a Chrome extension (so you don't have to always keep that annoying Bookmarks Bar sticking out). This is NOT officially supported by the Plex Project (yet).
Download a compressed file of the extension and decompress it. Then open Chromium/Chrome and in the Menu choose More Tools and then Extensions. Then hit Load Unpacked Extension and enter the folder you decompressed the files into. The extension will then install.
