## Description

Formidable is an extension that populates forms with data generated by Faker.js (<a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/9f2939b11e30e1d2fc83662ef557e083ebe9c8aad9b8fe68e9069897c764db3e/https%3A//fakerjs.dev/" rel="nofollow">https://fakerjs.dev/</a>) via the context menu and a sidebar.

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