Formidable Firefox

Formidable

By: vifito Add-on
Manage form fields with data generated by the Faker.js library. (spanish version)

Features & Capabilities

Formidable is an extension that populates forms with data generated by Faker.js (https://fakerjs.dev/) via the context menu and a sidebar.

  • Context Menu: Right-clicking on any fillable field (input, textarea, select, or editable content) displays the Faker menu with categories of random data:
  • Person (name, surname, email…)
  • Internet (email, username, password, URL, IP…)
  • Address, Phone, Company, Finance, Text, String, Number, Date, Color, and Boolean.
  • The generated value is written to the field and also copied to the clipboard.
  • Form Selection: The Select Form option opens the sidebar and extracts all fillable fields from the form (or page) along with a unique CSS selector for each one.
  • Side Panel (Editor):
  • Assign each field a Faker value, a literal value, a random selection (for select, checkbox, and radio), a checked/unchecked value (checkbox), or custom JavaScript.
  • The JavaScript is evaluated in the main world of the page (it has access to faker, el —the actual element— and the entire DOM). It executes after static values, so it can copy the value from another already filled field (e.g., repeating the password).
  • Save, update, and delete configurations; when saving, the default name is assigned starting from the first h1 on the page or, if none exists, from the text of title.
  • Apply configuration: from the side panel or from the Apply configuration submenu in the context menu.
  • Persistence: Configurations are saved in sqlite.

Is Formidable 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.

Formidable requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
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.

Formidable is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.

Risk likelihood analysis details
  • High This extension was recently updated in the past month. New updates may not be stable or safe.
  • High **** ********* *** ******** ****** *** ********** *** *** ** ****** ** *****
  • High **** ********* *** *** **** ****** ********* ********** *** *** ** ****** ** *****
