Instead of opening Developer Tools, copying code, or repeating the same steps across pages, Inject JavaScript allows you to inject JavaScript with a single click. Scripts appear only when the current page matches your rules, keeping the interface clean and relevant. Why install Inject JavaScript? • Run JavaScript instantly Inject custom scripts into the current page with one click. • Context-aware actions Scripts only appear on pages where they apply, based on URL and page content. • No DevTools required Faster and more convenient than pasting code into the console. • Flexible and customizable Control when scripts appear and what they run. • Local and private All scripts run locally in your browser. No accounts. No tracking. Inject JavaScript is ideal for developers, testers, learners, and power users who want more control over how web pages behave — quickly, safely, and on demand.
