Frame Sync Fork Firefox

Frame Sync Fork

Frame Sync Fork is a solution for wireless audio delay, syncing video with audio for lag-free playback.

Features & Capabilities

If you use an adblocker (like uBlock Origin) and you find the sync is not active at the start of a Youtube video, pausing and un-pausing the delay by clicking on the button that you see when you click on the extension icon should get the sync working turned on.

This is based on a fork made by tngusouk528 of Frame Sync made by Trogen898 which fixes the issue where the framerate is limited to 30FPS.

Frame Sync is the best solution for resolving wireless audio delay. You’ll enjoy perfectly synced audio and video when streaming PC audio to Bluetooth or wireless headphones pr speakers using TuneBlade, Airfoil, or Sonos. It intelligently delays video playback to match the sound delay from wireless transmission, giving you a smooth, seamless media experience without any frustrating lag.

This extension isn't built for any specific website—it works on all websites. No matter where you're watching, it ensures your video and wireless audio are perfectly synced across all platforms.

Note: This extension is still in early development. While I'm excited to share this preview version with you, more convenient features are currently in progress. Stay tuned for future updates!

Is Frame Sync Fork 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.

Frame Sync Fork requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood measures the probability that a Firefox add-on may turn malicious.
