Have you ever been typing in a web form and had it close down unexpectedly, taking a huge blog posting or a forum post or some other long post with it? Of course you have, I have had that happen many times! I use a Firefox plugin called Lazarus, available from http://lazarus.interclue.com/ as well as the firefox addon site. It will save your form information as you type it so if something bad happens and you lose the page you will be able to pull the information back. You can do this a couple of ways , right click on the webpage and select recover form, which brings up a dropdown with the available save points, or you can right click the text box you are filling and select recover text which will give you a dropdown that has all of the text fields you have enterred in that box. Comes in very handy!! I even use it to enter contests, if you have a long form you fill out like everyday then you can just right click it and recover form and it will fill all of the fields on the form except passwords.
They even have a plugin for chrome if you happen to use that browser.
Hopefully that will help someone else out like it did me.
