This is an extension for Google Chrome that allows you to persistently set the version on docs.python.org to use. For instance, setting it to 3.5 and then browsing to the docs for 2.7 will automatically redirect you to the version you specified.

The extension is not (yet) available on the Chrome Store, so it must be installed manually:

1. Download the extension (version 1.0)
2. Open the Chrome Extensions page and drag the extension in and drop it on the page.
3. You will see a popup asking if you wish to install the extension.

No warranty is given - use at your own risk!

Tested on Google Chrome 44 beta (Linux) but should work anywhere.
