If you've ever been filling in a big text entry on a form only to lose the page (accidental click, browser crash, server crash, etc), you know how painful this can be. Not only does it suck that your work is lost, but then you have to repeat it again.

AutoSaveTextToCookie completely solves this problem. It's a plug-in for Firefox that saves your text entries every time you hit a key. Basically, it's a short-term key logger for text areas. If something happens and you lose the page, you can get all of your text entries back quickly and easily.
