What is Anesidora?
An unofficial Chrome extension that lets you play Pandora Radio straight from your browser, without the nuisance of another open tab. Anesidora blocks ads, and removes listening limits. You can even control Pandora by typing commands into Chrome's address bar.
The official version has been removed from the Chrome Web Store, though you can still download the extension from the website link provided.
The website and the app are no longer available.
