Used to use Lazarus, switched to Form History Control (which stopped working with Firefox v57), was hoping this would replace the other two but, at least in the current version of Firefox, all this app does is give you a button to clear the history, it doesn't actually give you the option to restore data previously entered in forms.

I am also a former Lazarus add-on user, and have been looking for something to take its place, and Simple Form History just looks like it could be the one !
What it needs now are easy ways to access this save data, through right-clicks on the current page for example.

It's really an alpha version at the moment and I don't understand the version number, should be 0.1.
But I hope it will be a successor of Lazarus Add-On and will be as good as Lazarus was. I would love it.
So these four stars are the stimulus to work on it. :)

At the moment I am not sure that it does what it should do. First short test says no.
