Welcome back!
Imagine this! You just typed a page-long comment and hit the submit button – and you were greeted with a server time-out error! The page-long comment vanished without a trace, all your efforts to choose the balanced words gone down the drain. If you were a victim of such an atrocity, time to get hold of Lazarus – a magnificent Firefox form recovery tool.
What Lazarus does?
- Lazarus is a free add-on for the Firefox browser which backups the data you’ve entered into web forms. It then stores this data so you can easily recover it if you need to re-enter it for some reason.
- Lazarus restores the entire form at once saving you the trouble of going through individual fields
- It also restores multiple data inputs in the same form, for easy recovery of multiple forms
How do you use it?
To use Lazarus after you have installed it, right-click on the field for which you want to restore the data on a forms page. In the right-click context menu, you find the Recover form option clicking on which will help you recover your forms with ease.

In the above example, we restored the Comment field. Two entries of data were there, choosing one will restore the entire form entries to which that entry belonged. So it would not only restore the comment but also other fields like username, email etc.
Here in the Recover form option:
- (A) stands for Autosaved data
- (S) stands for Submitted data
Lazarus works in the background and also appears as an icon in the Firefox status bar. It stores data locally in a SQLite database in your Firefox profile folder and you can set a Master Password to secure your data. It also adds an option to set an expiry date to saved information and also to clear Recovered Forms data.
All in all, Lazarus is a really handy tool to be added to your Firefox add-ons list.
