Mac Autoscroll

About

Bring the classic Windows middle-click autoscroll to Chrome on macOS.

Press your mouse's middle button (wheel) anywhere on a page and a small origin marker appears. Move the mouse away from that point and the page scrolls in that direction — the farther you move, the faster it goes. Click again, press Esc, click elsewhere, or scroll the wheel to stop.

Features • Middle-click to start and stop — just like Windows. • Speed is proportional to how far you move from the origin, with a dead zone so it holds still. • Works vertically and horizontally, on the whole page or inside nested scroll areas and iframes. • Click the toolbar icon for a settings panel to tune max speed, dead-zone radius, and the acceleration curve — changes apply instantly.

Privacy Mac Autoscroll reads no page content, makes no network requests, and collects no data. Your settings are stored only in Chrome's own synced storage.

Note: this extension uses the real middle mouse button, so a mouse with a clickable wheel (or a mouse configured to send a middle click) is required. Trackpad-only setups are not supported.
