Efficient Speed Control for HTML5 and WebGL

HTML5 Universal Speed Hack is a browser extension for Firefox designed to enhance user control over HTML5 and Unity WebGL games, as well as interactive web applications. This tool allows users to manipulate time-related functions, enabling features such as speeding up gameplay, pausing, or altering the timing of animations and events. The extension is particularly beneficial for gamers, developers, and quality assurance professionals who require precise timing adjustments during testing or gameplay.

The extension offers both a free version, which provides basic speed control up to 3x and manual timer function management, and a VIP version available through Patreon that unlocks advanced features. The VIP version allows speed adjustments from 0.1x to 100x, supports background tab functionality, and provides an enhanced user interface. With functions like setTimeout, setInterval, and requestAnimationFrame, users can efficiently control the execution timing of web applications, making it a valuable tool for anyone looking to optimize their web experience.
