HTML Universal Speed Controller

A powerful browser extension that allows you to control the speed of HTML websites by manipulating various timing methods. This extension provides fine-grained control over website timing functions and includes features like auto-speed for specific sites and mobile optimizations.

Features

Core Speed Control

• Control website speed through a multiplier (0x to any value)
• Affects multiple timing mechanisms:
• setInterval
• setTimeout
• performance.now()
• Date.now()
• requestAnimationFrame

Advanced Features

• Auto-Speed Sites: Configure specific websites to automatically run at predefined speeds
• Mobile Optimizations: Special handling for mobile devices with performance considerations
• Auto-Click Close: Automatically closes elements with .close-btn class
• Granular Control: Enable/disable individual timing method speed control
• Site-Specific Settings: Different speed settings for different websites

Technical Features

• Persistent settings storage
• Background service worker for extension management
• Content script injection for page manipulation
• Cross-browser compatibility (Firefox 79.0+)
• Mobile device detection and optimization
