# Does the extension work on all browsers?

## Learn which browsers support the FreJun Chrome Extension, why Chromium browsers work best, and how to ensure smooth click-to-call and CRM integration performance.

The **FreJun Browser Extension** is built to enhance calling workflows by enabling [click-to-call](https://frejun.com/click-to-call/), CRM syncing, and real-time call tracking directly from your browser. However, to ensure consistent performance and full feature access, browser compatibility plays a critical role.

Currently, the FreJun extension is optimized for **Chromium-based browsers**, ensuring a stable, secure, and seamless experience for sales, recruitment, and support teams. This article explains which browsers are supported, which are not, and best practices to get the most out of the FreJun extension.

The FreJun Chrome Extension is designed primarily for Google Chrome, but it also works seamlessly on Microsoft Edge (Chromium-based). This ensures users can benefit from FreJun’s powerful features on both of these modern, Chromium-supported browsers.

### Supported Browsers

1. Google Chrome (Recommended)
   
     - Full feature compatibility
     - Most stable experience
     - Regularly tested and updated
2. Microsoft Edge (Chromium-based)
   
     - Fully supported
     - Works just like Chrome, as it’s based on the same engine
     - Ideal alternative if you're using Edge in a corporate environment

### Unsupported Browsers

The FreJun extension is not supported on:

- Mozilla Firefox
- Safari
- Internet Explorer
- Other non-Chromium browsers

Using these may result in:

- The extension not loading or functioning
- CRM integrations being unavailable
- Click-to-call or call tracking features breaking

### Recommendation

For the best performance:

- Use Google Chrome or Microsoft Edge
- Keep your browser updated
- Grant necessary permissions like microphone and tab access for smooth operation
