How to retrieve a lost text after your browser didn't submit the text

"For Firefox, there is an add-on named ""Lazarus"" which gives you exactly what you want: addons.mozilladotorg/en-US/firefox/addon/6984

This is from the description of the add-on:

Never lose anything you type into a
web form again! Lazarus securely
auto-saves all forms as you type, so
after a crash, server timeout, or
whatever, you can go back to the form,
right click, ""recover form"", and
breathe a sigh of relief."
