Gesturefy

Gesturefy is a highly popular, open-source mouse gesture extension primarily built for the Mozilla Firefox browser. It allows you to navigate the web, manage tabs, and execute browser commands simply by moving your mouse while holding down a specific button. It acts like customizable keyboard shortcuts, but specifically designed for a mouse to enable quick, single-handed browsing. Core Features

Standard Mouse Gestures: Execute actions by moving the mouse (e.g., drawing a line down to scroll to the bottom of a page).

Rocker Gestures: Trigger commands by holding one mouse button and clicking another (such as right-click while holding left-click).

Wheel Gestures: Execute shortcuts by scrolling the mouse wheel while holding down a mouse button.

Massive Command Library: Choose from more than 80 predefined commands like closing tabs, opening links, reloading pages, or navigating history.

Advanced Commands: Supports special custom functions like popups, user scripts, and cross-add-on operations.

Visual Customization: Tailor the interface with light, dark, and high-contrast themes, and change the appearance and color of your gesture tracking trails. Important Limitations

Mouse Only: It is explicitly designed for a physical mouse and does not work well with laptop touchpads.

Restricted Pages: Due to strict browser security rules, it cannot function on internal browser settings (about:addons) or official extension market pages like the Firefox Add-ons Blog.

Privacy & Permissions: To trace mouse tracks across the web, the extension requires permission to access data on all websites. However, the developer explicitly states on their Robbendebiene/Gesturefy GitHub repository that it collects zero user data. Availability

While it remains a staple for Firefox users, an unofficial Chromium adaptation called Cesturefy brings the same functionality to Google Chrome and Microsoft Edge.
