For Tampermonkey v5.3+ on Chromium-based browsers, you must enable either the "Allow User Scripts" toggle (Chrome/Edge 138+) or Developer Mode. This is required in addition to the userScripts permission so that the browser shows a clear warning and you explicitly allow userscript execution.

• Why is this required?

  • Userscripts need both the userScripts permission and either the Allow User Scripts toggle or Developer Mode enabled. The extra step is a browser safeguard to ensure informed consent for running userscripts.

• Steps to enable

  • In desktop Chrome/Edge 138+:
    • Right-click the Tampermonkey icon → Manage Extension.
    • Enable the "Allow User Scripts" toggle.
  • Or enable Developer Mode:
    • Go to chrome://extensions or edge://extensions.
    • Turn on Developer mode (top right).

Please enable developer mode to allow userscript injection. Click here for more info how to do this. https://www.tampermonkey.net/faq.php#Q209

Note: When enabling "Allow user scripts", the extension can run code not reviewed by Google. Only enable this if you trust the source and understand the risks.

• Install the matching userscript extension for your browser (Tampermonkey/Violentmonkey).
• Install TimerHooker from GreasyFork: https://greasyfork.org/en/scripts/553657-timerhooker-2026
• After installation, open any website. A floating “energy ball” appears on the left. Hover to reveal acceleration options.
• Click to speed up or slow down. The floating badge shows the current multiplier.

• Ctrl + = or Ctrl + > : Increase timer speed (default +2)
• Alt + = or Alt + > : Increase by multiples (default ×2)
• Ctrl + - or Ctrl + < : Decrease timer speed (default -2)
• Alt + - or Alt + < : Decrease by multiples (default ÷2)
• Ctrl + 0 or Alt + 0 : Reset to 1×
• Ctrl + 9 or Alt + 9 : Open custom speed input
