About

**Who needs this?**

Web developers and QA engineers testing if their websites correctly serve WebP/AVIF images with proper fallbacks for older browsers.

**What problem does it solve?**

Modern browsers support WebP and AVIF, making it difficult to test fallback behavior. This extension lets you simulate browsers with different image format support.

**Available Modes:**

• **No WebP/AVIF Support** - Request only PNG/JPEG/GIF (legacy browsers)
• **WebP Only** - Prioritize WebP format
• **AVIF Only** - Prioritize AVIF format  
• **OFF** - Default browser behavior

Simply click the extension icon and select a mode. Changes apply instantly to all new image requests. Perfect for testing CDN configurations, debugging image delivery issues, and ensuring your site works for all users.
