I have not relied on this much but it has saved my butt a few times and I avoided retyping everything in a text box. There have been a few places where it did not save the text but it seems to work most places. Also, as one previous 3 star review pointed out, the copied recovered text often includes a bunch of html code which is annoying. It's still better than retyping a long entry and you can delete the coding or I think you can highlight and copy the recovered text rather than using the "copy" button to avoid this problem.
