I have two playback devices in my computer, my headset, and my PC speakers. Sometimes I need to change which of these two devices will play sound, based on whether I am using my headset or not. I change which device is playing sound by right-clicking the speaker icon on my task bar and choosing the device I want to play sound on to "default". Most programs, including iTunes, Google Chrome, most video games, even hated Internet Explorer are all able to play sound on whatever device is selected to "default", even if said programs were playing sound at the moment the default device was changed, and they can dynamically change output devices. Every program but Firefox. With Firefox, I have to close and re-open the browser, which is a small hassle, but a hassle nonetheless. Is there a way to "fix" this? I've looked and saw no option in the browser, but perhaps an add-on/extension? Thank you for your help.
