This extension remembers and synchronises your volume for videos on Facebook.
Don't you just hate the fact Facebook videos are always playing on 100% volume? I do, especially when wearing headphones. This tiny extension fixes just that and adds the functionality we all know and love from YouTube, Soundcloud and many others. Whenever you change the volume of a video on Facebook, it will make sure every other video will have the same volume, even after restarting Chrome.
