Style Engine Is Now Live on Chrome, Edge, and Firefox
We’re happy to announce that Style Engine is now officially available on all major desktop browsers.
After a full development and review cycle, the extension has been published on:
- Google Chrome
- Microsoft Edge
- Mozilla Firefox
Style Engine is a lightweight browser extension that lets you apply your own custom CSS and JavaScript to websites — either globally across the web or on a per-domain basis.
It was built for developers, designers, QA workflows, and power users who want precise control over website appearance and behavior without modifying server-side code.
What Style Engine offers
- Global CSS and JavaScript rules for all websites
- Per-website rule management with isolated domain-based settings
- Popup editor for fast adjustments on the current site
- Options panel for full rule and settings management
- Backup and restore support for local configuration portability
- Multi-language interface
- Local-only behavior with no tracking and no remote code

Built with control in mind
Style Engine was designed around a simple principle: your browser, your rules.
The extension stores its configuration locally, runs only the rules explicitly saved by the user, and does not collect analytics or browsing data.
This first public release establishes the foundation for future improvements, UI refinements, and broader language support.
