DevTools Media Panel Firefox

DevTools Media Panel

DevTools panel that displays technical details about media elements and webrtc on the current page; intended primarily for web developers to understand media playback issues on their sites, and for users to provide more informative bug reports.

Features & Capabilities

The DevTools Media Panel is a powerful Chrome extension that integrates seamlessly into your browser's Developer Tools, adding a dedicated panel named "Media-Webrtc". Designed primarily for web developers and advanced users, this tool provides comprehensive technical details about media elements and WebRTC connections on the current page.

Within the media tab, users can inspect each video element’s playback state, including various diagnostic parameters that help identify issues with media playback. The WebRTC tab presents detailed information about each PeerConnection and GetUserMedia (GUM) instance, making it easier to troubleshoot streaming and peer-to-peer communication problems. This extension empowers developers to better understand and resolve media-related challenges on their websites, while users can supply more insightful bug reports.

Is DevTools Media Panel Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

DevTools Media Panel requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
