Webextension update issues If you have problems updating the extension, remove it completely and make fresh install.

Formlet is Firefox extension for saving form data to bookmarklets.

It was inspired by Form Saver, which unfortunately does not work since Firefox 4.x. While Formlet is completly new and independent extension, the basic idea has been preserved - forms data is saved as autofilling bookmarklets.

Why another form filler?

At Mozilla Addons you can find plenty of form fillers (eg, Autofill Forms, AutoFormer etc). But personally I liked the simplicity of Form Saver, which was saving form data to a simple bookmark. It is sufficient for form testing and does not require complicated configuration. What's more - bookmarklets created in this way will work also in other browsers!

How it works

  1. Fill out a form.
  2. Right click on it and select "Save form with Formlet" from context menu
  3. Confirmation notification will be show
  4. Find bookmark and click it
  5. Bookmark will fill the form with saved data.

Is Formlet Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Formlet requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Formlet has earned a fairly good reputation and likely can be trusted.
