Thread:Extension talk:ClientsideDrafts/How to access Drafts

I've installed it and it does say it has saved a draft but how do i access the drafts. If I quit after typing and leave to come back to page I don't see it in the history of the page. In addition, what does it mean when you say it works on clients that use HTML5 Storage and JSON API's. In other words, in lay terms how can I make sure this is the case?

Thanks for this great extension, it really adds a very important feature.
