Rated 5 out of 5 stars
Using Firefox 29 (Beta) - so everything in url bar, removed 'Currently Playing' , 'Downloads' and 'spacers' to make room for all my add-ons icons. 'Currently Playing' never showed what was playing so won't miss it!
Left click 'current time/duration' for volume control. (for Jenniechenniee below)
Excellent add-on, Thank you!!
