Video Volume Sync is a free Chrome add-on developed by Nick Waelkens. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This handy extension aims to solve the common annoyance of videos on Facebook playing at full volume, particularly when using headphones.

The main feature of Video Volume Sync is its ability to synchronize the volume for videos on Facebook. Similar to popular platforms like YouTube and Soundcloud, this add-on ensures that when you adjust the volume of one video on Facebook, the same volume setting will be applied to all other videos, even after restarting your browser. This eliminates the need to constantly adjust the volume for each individual video, providing a more seamless and consistent viewing experience.

With Video Volume Sync, you can finally bid farewell to the frustration of unexpectedly loud videos on Facebook. This simple yet effective add-on brings the familiar volume synchronization functionality to your Facebook video viewing, enhancing your overall browsing experience.
