what is the _lr_id_ localstorage item and where does it come from?

Question

It appears that localstorage contains an item called _lr_id_ by default. It shows up on all browsers and recreates itself when localstorage is cleared. I tested this on an OSX laptop and a Linux laptop in 4 different browsers, so it's definitely not a plugin. It's not just on my site, there are other websites that have it too, like reactivepad.com. It contains a JSON object with a guid labeled userID like this:

{"userID":"a11f6077-86b4-47c5-ae8d-58859682b033"}
