This extension makes it easy to fill out web forms by saving and managing multiple form presets for different websites. First fill your form then press "Record". This will save the data entered in a preset, depending on the current website. Next time you visit the website, the preset can be selected in the extensions' window to automatically fill the form for you. Multiple presets can be saved for one website. You can edit the saved data or the preset names in the "Options" screen of the extension.
