Hey thechocolate one,

I've tested Animal Forest BGM on Firefox (Beta) 57 and am unable to reproduce this issue! My first thought is that this might have to do with the automatic media playback detection feature. Try disabling that feature and see if the issue persists. If it disappears, check to see if any of your tabs or other WebExtensions emit or are capable of emitting audio-- that might be the cause!

I'll attempt to reproduce your issue on Firefox (Stable) 57 and let you know if I am able to reproduce this issue. If you're running a version of Firefox other than 57, please let me know so that I can test it with the appropriate version!

Thank you for the feedback!

EDIT: I've made attempts to reproduce this bug on the stable version of Firefox 57, but with no success. Please try disabling the media playback detection feature-- if that works, please let me know!

EDIT 2: I'm glad to hear that the add-on is now working correctly. Thank you so much for updating your review!
