About this extension

Changes in this fork:

Universal HTML5 Video Player Support: Runs on all websites (:///*) using dynamic MutationObserver detection to attach speed controls to any <video> element on static pages and single-page apps (SPAs) alike (Twitch, Vimeo, custom players, etc.).
Native Player Integration & Fallback Overlay: Renders speed indicators and controls directly inside YouTube's bottom control toolbar (.ytp-right-controls), with automatic fallback to an on-player overlay for generic HTML5 video players on other websites.
Preset Speeds: Configurable list of preset speeds (e.g. 1.5, 2) rendered as quick one-click buttons.
Modern Key Handling & Simplified Options: Replaced legacy numeric key code mappings (keycodedict.json) with standard KeyboardEvent.key matching. Options - UI uses clean text inputs supporting multiple comma-separated shortcut keys.
Manifest V3: Built for modern Firefox WebExtensions (Manifest V3).
