If you have feature ideas, feedback, or run into any issues, please feel free to contact me by email. I read every review and message, and your feedback helps shape future updates to InjectJS. If InjectJS has been helpful to you, I’d also greatly appreciate a review and a five-star rating on the Chrome Web Store. Your support is a meaningful part of keeping the project improving. InjectJS 1.3 is a browser extension for writing, managing, and running custom JavaScript on websites you choose. Built for developers, testers, automation enthusiasts, and power users, it lets you customize page behavior without modifying a website’s source code. What’s new in 1.3: ✔ Completely redesigned interface with a cleaner, more refined experience ✔ Upgraded Popup workflow: create, edit, preview, format, save, run, and delete scripts without leaving the current page ✔ New execution timing options: page start, DOM ready, page idle, scheduled time, repeating interval, and manual execution ✔ Optional iframe execution and script execution-order control ✔ Domain, Chrome URL Pattern, and regular-expression matching ✔ URL allowlists and exclusion rules for precise script targeting ✔ Local JavaScript and browser API code completion ✔ Choose between the page main world and an isolated user-script world ✔ Light, dark, and system-following themes; Chinese and English interface support ✔ Import/export for local backups ✔ Existing scripts and preferences from earlier versions are automatically migrated—upgrade without losing your data InjectJS 1.3 also introduces clearer onboarding for Chrome’s “Allow User Scripts” permission. Enabling it allows scripts to run at the earliest page-loading stage; if it is not enabled, compatible scripts can still run after page loading completes. Whether you are testing ideas, automating repetitive actions, modifying website behavior, or creating a more personal browsing experience, InjectJS gives you flexible, local control over your own JavaScript on the web.
