Form Field Auto-Tab

WHAT IT DOES

Form Field Auto-Tab eliminates the need to manually press the Tab key when filling out forms. When you type into a text input, textarea, or select dropdown and reach the maximum character length defined by the website, the extension automatically advances focus to the next form field. This is particularly useful for filling out structured forms like address fields (zip codes, state abbreviations), phone number segments, credit card numbers, date fields, and any other form where fields have fixed character limits. The auto-tab behavior is configurable: you can set a custom delay in milliseconds before the focus advances, giving you time to review your input before moving on. A single toggle switch enables or disables the feature instantly, and domain-specific settings let you customize behavior for different websites. The extension supports all form field types except password, hidden, and file inputs, which are excluded for security and privacy reasons.

WHERE IT RUNS

The extension works on every website with HTML forms, including e-commerce checkout pages, registration forms, login screens, survey platforms, CRM systems, admin panels, and any other web-based form interfaces. It runs locally in your browser, processing form interactions in real-time without sending any data to external servers. The auto-tab behavior applies immediately as you type and continues to work as you navigate between fields. The extension supports all major browsers and adapts to both desktop and mobile viewports seamlessly, with touch-optimized focus behavior for tablet and phone users.

HOW TO USE

After installation, click the extension toolbar icon to open the Form Field Auto-Tab panel. The panel shows the current status (enabled or disabled) and your current delay setting. To enable or disable auto-tab globally, use the toggle switch. To customize the delay before focus advances, enter a value in milliseconds (0-2000) in the delay input field and click "Apply Delay." A delay of 0ms advances focus instantly, while a higher delay gives you more time to verify the field content. For per-site customization, click "Apply to This Site Only" to save your current settings for the specific website you're on. Click "Reset Site to Global" to revert a site to your default settings. If the extension doesn't detect new form fields added dynamically (e.g., in single-page applications), click "Refresh Listeners" to manually reattach the auto-tab behavior to all form fields on the current page.

THE ACTUAL MECHANISM — EVENT-DRIVEN LISTENER PIPELINE WITH MAXLENGTH DETECTION

Form Field Auto-Tab works by attaching input event listeners to every eligible form field on the page. When a user types into a field, the listener checks if the field has a `maxlength` attribute and whether the current input value has reached or exceeded that limit. Upon detecting a full field, the extension uses a two-step process: first, it dispatches both `input` and `change` events to ensure any React or Vue state updates are triggered (preventing the framework from overwriting the value on the next render). Second, it identifies the next focusable field by walking the DOM from the current field—first checking within the same form, then falling back to a page-wide query if no next field is found within the form. The extension respects `disabled` and `readonly` attributes, skipping fields that cannot accept focus. For security, password, hidden, and file inputs are explicitly excluded from the listener pipeline. All focus changes are wrapped in a `setTimeout` using the user-configured delay, preventing race conditions and ensuring smooth navigation. For dynamically generated form fields, a MutationObserver watches for DOM changes and automatically reattaches listeners to new fields, maintaining the auto-tab behavior across page updates.

THE PANEL

The settings panel is a lightweight, draggable overlay that appears in the center of your screen. You can reposition it by clicking and dragging the title bar; release it near the screen edge and it will snap into place automatically. To collapse the panel into a compact title bar, click the minimize button, expanding it again with the same control. The panel is fully responsive, adapting to different screen resolutions with a minimum width of 300px and a maximum of 480px. Press the Escape key at any time to dismiss the panel without applying changes. All controls—the enable/disable toggle, delay input and apply button, per-site settings, refresh button, and reset options—are accessible within a clean, high-contrast interface that respects your system's color scheme.

PLEASE NOTE

This extension requires the free BotGentz companion extension to be installed and active, which provides the underlying event handling engine and cross-browser compatibility layer. Because websites frequently update their form structures and JavaScript frameworks, certain complex web applications may occasionally require manual listener refresh or script updates to maintain full auto-tab functionality. The extension will automatically check for updates weekly and notify you when a new version is available. No personal data, browsing history, form data, or input values are ever collected, stored, or transmitted. All settings are saved using the browser's local storage API and remain solely on your device. The extension does not inject ads, trackers, or analytics of any kind.
