If you ever have the problem of forgetting you were writing something and closing a window, or accidentally navigating away from the page on which you are composing, this is the browser extension to save your ass: Form History Control.

In kbin I especially have this problem as I get logged out constantly for some reason, for example while I am composing even a fairly short comment, and if I submit while logged out the text vanishes. But everything is stored in the extension. It is local to your machine where it will be secure.

I am using it for a year or two now and it has been flawless. It doesn’t cause any slowdown in browser performance. It is unnoticeable until that moment you need it.
