Works great on Youtube. However, most other websites I use I have to open the video in a new tab to get audio (or in one specific instance, to get the video play at all). The lack of any easy way to turn the extension off without going into Firefox's full menu means that this app becomes a hassle very quickly.

this works ok for youtube but it completely breaks (mutes) audio on other sites, like with Imgur especially. None of the files with audio will playback anymore, unless the file is saved and viewed elsewhere, or in a private session without this addon. Please fix this so mp4 audio is not muted?

Edit: thanks for working on a fix
