AutoFill Forms (WebExtension)

Fill out web forms automatically with a single click

Features & Capabilities

The AutoFill Forms (WebExtension) is a powerful and user-friendly Chrome extension designed to fill out web forms instantly with a single click. It supports multiple user profiles allowing you to manage different sets of form data easily. You can create or update profiles by detecting data from filled forms, making profile management seamless.

Key features include generating random strings from Regular Expressions, perfect for creating complex passwords or security question answers. The extension can also generate secure random passwords and copy them directly to your clipboard for convenience. It supports importing and exporting preferences for easy configuration and stores profile data securely within your browser without creating backups for privacy. Additionally, it efficiently handles forms with non-standard field matches and operates with minimal resource usage in the background.

User Reviews

Users praise the add‑on as reliable, time‑saving, and powerful (robust rules and multiple profiles) with long‑term maintenance. However, multiple reviewers report inconsistent autofill behavior, a confusing UI/learning curve, variable compatibility with some form types, and weak or broken documentation.
Pros
  • Many users find it reliable and long‑lasting—several reviewers say it 'works perfectly' and have used it for years.
  • Saves time by auto‑filling repeated data — 'input once & never do that again' and it prevents repetitive typing.
  • Powerful rule system and support for multiple profiles, which helps handle complex or unusual form layouts.
  • Actively maintained/updated (rewritten when Firefox changed policies) — longtime users report continued functionality.
Cons
  • Inconsistent behavior: several users report it fails to autofill or never suggests saved values for some sites or profiles.
  • Steep learning curve and awkward UI—multiple reviewers call the interface hard to manage or 'bizarre.'
  • Compatibility varies across form types/fields (some users report issues with certain forms or field types).
  • Documentation/help is lacking or broken—users report difficulty finding working help links or guidance.

Just doesn't work for me. Values are saved in the profile, but never suggested for an autofill.

Is AutoFill Forms (WebExtension) 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 (WebExtension) requires very minimum permissions.
