Features & Capabilities

Autofill Forms is a powerful Chrome extension designed to simplify the process of completing online forms. Using either a convenient toolbar button or the Alt+Shift+F keyboard shortcut, users can quickly fill out web forms with custom data.

Users configure autofill rules by specifying CSS Selectors tied to form fields along with the corresponding values, allowing full customization per website or globally. All settings and data reside locally on your device, ensuring maximum privacy with no information sent to external servers. This extension requires minimal permissions, only storage and active tab access. For additional details, guides, and bug reporting, users can visit the extension's homepage. Autofill Forms is perfect for anyone looking to streamline repetitive form entry while keeping their data secure and private.

Writing the rules is a bit difficult, but it works well for my purpose. I regularly create polls on a page based on Framadate. Autofill Forms pre-fills the forms, so I save some manual work. What I would like to have is an option to export/import the rules in some text format. This would allow me to use the same rules in different browsers.

Is Autofill Forms 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.

Autofill Forms does not require any sensitive permissions.
