Universal Auto-Scroll to Bottom

WHAT IT DOES

Universal Auto-Scroll to Bottom adds a floating button and keyboard shortcut that instantly scrolls you to the bottom of any webpage. With configurable scroll speed and smooth acceleration, the tool provides a polished scrolling experience that feels natural and controlled. Whether you are navigating long articles, reaching the end of infinite-scroll feeds, or quickly jumping to the footer of a page, this tool saves you from endless manual scrolling. The floating button stays accessible on every page, and the keyboard shortcut (Ctrl+Shift+End) lets you trigger the scroll without lifting your hands from the keyboard.

WHERE IT RUNS

This extension works on any website across the entire web. It functions on articles, documentation pages, social media feeds, infinite-scroll pages, and any other scrollable content. The tool works across all domains and adapts to dynamically loaded content and single-page applications.

HOW TO USE

Install the extension and navigate to any webpage. A floating scroll button appears in the bottom-right corner of the screen (a down arrow icon). Click the button to start scrolling smoothly to the bottom of the page. Press Ctrl+Shift+End on your keyboard to trigger the scroll without clicking. Use the overlay panel to customize your experience: choose between Fast, Medium, or Slow scroll speeds, toggle Smooth scrolling on or off, enable Auto-scroll on page load to automatically scroll to the bottom when a page loads, and toggle the tool on or off for the current site. Click "Scroll to Bottom Now" from the panel to trigger the scroll manually, or "Cancel Scroll" to stop an ongoing scroll animation.

TECHNICAL SECTION — SCROLL ANIMATION ENGINE

The extension uses a requestAnimationFrame-based scroll engine for smooth, performant scrolling. When triggered, the engine calculates the remaining distance to the bottom of the page (document height minus viewport height minus current scroll position). It then applies a speed factor determined by the user's selected speed setting — Fast uses 0.92 (covers 92% of remaining distance per frame), Medium uses 0.96, and Slow uses 0.99. This exponential decay approach creates a natural acceleration curve where the scroll starts quickly and slows down as it approaches the bottom, providing a smooth and comfortable visual experience. Each animation frame calculates the new position using the formula newPos = currentPos + remaining * (1 - speed) + 2, where the small constant ensures the scroll never stalls. The engine cancels gracefully when the user scrolls manually, and the animation loop is managed through requestAnimationFrame for optimal performance and battery efficiency.

THE PANEL — DRAG / PER-SITE POSITION / SNAP / COLLAPSE / RESIZE / ESCAPE

The overlay panel is fully interactive and designed for seamless multitasking. Drag it anywhere on the screen using the handle at the top of the panel; the position is saved per site so it stays where you left it across sessions. The panel includes a snap-to-edge feature that gently anchors the overlay to the nearest screen edge when released. Click the collapse button to minimize the panel to a compact pill showing the current scroll status; expand it again with a single click. Resize the panel vertically by dragging the bottom-right corner to view more controls. Press the Escape key at any time to instantly close the overlay; it reappears on the next page navigation or refresh.

PLEASE NOTE

This extension requires the free BotGentz companion extension to function, as it provides the underlying content script injection and cross-origin communication framework. No personal data, browsing history, or page content is stored, transmitted, or shared. Settings are stored locally in your browser using GM_setValue and are never sent to any external server. The extension does not access or store login credentials, financial data, or personally identifiable information. On pages with infinite scrolling that load content dynamically as you scroll, the scroll-to-bottom may appear to stop before reaching the actual "end" of the content. A manual scroll or re-clicking the button will trigger additional scrolling to load more content. The floating button may overlap with other page elements; use the per-site toggle to disable the tool on sites where the button is intrusive.
