Two-Finger Back

Swipe left or right with two fingers to go back and forward, on a precision touchpad. This is not another approximation. It is a port of the gesture the browser already has: the thresholds, the circle that slides in from the edge, and the exact moment the navigation fires are all taken from the Chromium source, so muscle memory built on the native gesture keeps working. WHAT THAT MEANS IN PRACTICE • The gesture starts after 60 px of travel, and only when the swipe is clearly horizontal — a diagonal scroll never triggers it. • The circle turns blue at 30% of your display's longest side. That is the point of no return, and it is the browser's own number, not a guess. • It navigates when you LIFT YOUR FINGERS, not the instant you cross the threshold. Change your mind, swipe back under it, and nothing happens. • Momentum can finish a gesture but never start one, so a fast flick past a carousel will not throw you off the page. • If anything under the pointer can still scroll sideways — a carousel, a wide table, a code block — that scrolls instead. The gesture stays out of the way. • Pages that opt out with overscroll-behavior-x are respected. • Nothing happens when there is nowhere to go: no circle, no false promise. • The navigation goes through the browser itself, the same path as the toolbar back button, so single-page apps react to it exactly as they would to a real click. SETTINGS One switch, on or off. There is deliberately nothing to tune: every threshold is already the one the browser uses, and a sensitivity slider would only let you make it less faithful. IMPORTANT If your browser already has this gesture — Settings › Accessibility › "Swipe between pages" — turn that off first, or every swipe will navigate twice. WHERE IT DOES NOT WORK Browser pages (New Tab, settings, the Web Store) and cross-origin iframes do not allow extensions to run. macOS is left alone on purpose: the gesture is native there. PRIVACY No data is collected, none is transmitted, and there are no analytics. The only thing stored is whether you switched the extension on or off, kept locally on your machine.
