What is FormSaver?
FormSaver is a Firefox add-on that saves and restores form inputs such as input fields and text areas. It automatically captures and stores filled form elements, excluding hidden and password fields, every 10 seconds. The data is saved to local storage and can be restored on page load or when relevant changes are made to the page's DOM tree using the MutationObserver interface.

User reviews
It does something. You can tell because there's an annoying tell-tale flashes by the scroll bar. But that's the only way you can tell. There's no useful functionality in evidence. No instructions. The forms are not restored, which is the only thing it could be useful for. "Data is saved to local storage", it says. May be true but to all intents and purposes that seems to be write-only storage.
