The next entry in my series of Top Firefox Addons has saved my bacon on a number of occasions.

Imagine the following situation. You’ve spent half an hour in your favourite webmail client, meticulously writing an email, making sure that it is completely word-perfect. After reading it over for the third time, you decide it’s ready and you anxiously press the send button. Just as you breath a sigh of relief, “Error: Cannot connect to the server!” What?! Quick click back! The form is EMPTY! Aaaaaarrrrrrrrrrggggghhhhhhhhhhh! This is where Lazarus comes to the rescue.

Lazarus: Form Recovery continuously encrypts and stores everything you write as you type it. A simple user interface allows you to quickly bring back any content you lost due to a server error, browser crash, or inadvertently hitting the back button. All it takes is a single click. The current version includes 2048-bit RSA and 256-bit AES hybrid encryption, so you can be sure your data stays secure.

Lazarus works on ordinary web forms, WYSIWYG editors, and even AJAXified comment boxes, and will save you from pretty much any given server, browser, or connection problems that might otherwise cause you to lose your work, or that really pithy blog comment you struggled on for over an hour.

It’s not the kind of addon that you use (or even think about) every day, but when you need it, Lazarus will be there. Just don’t forget you installed it, because it won’t be as helpful once you throw your laptop out of the window. Check out the info page, or simply:
