Does not work for me at all

There doesn't appear to be an option to whitelist a site for exemption from pausing. As it stands, the addon prevents the ability to listen to YouTube in a background tab.

Very handy add-on when switching from one YouTube tab to another! This has been a thing I've been wanting even before migrating to Firefox but could not find an extension for until now. Many thanks to the developer who made this. My only wish is that the developer included exceptions for pinned YouTube tabs, especially for those that people intend to use as study music.

what version of firefox is being use in the screenshots?? How do you get the boxy toolbar icons?

still need more improvement not so much good. but i like it some it stop some times not

FF57 and All-HTML5 Youtube: Works like a charme! Thank you!

Not working.

Суть в чём. Ты включил другую вкладку или страницу интернета и видео на этой встало само на паузу. Вошёл обратно, тут же стало воспроизводиться ровно с того момента. Вещь!!!

No work

Уже открытые вкладки - да, при уходе с них ставятся на паузу и начинают проигрываться при переключении на них. Но новые открытые в фоне вкладки начинают проигрываться все одновременно. А дополнение нужно было в первую очередь для этого.

Seems to work fine, it could be icing on the cake if there were a play/pause button on the tab, indicating the state of playback. I understand it's redundant but it would be good just for the peace of mind.

I love add-ons that just 'work' like this one.

I did find one 'wish' though - an On/Off for use when listening to audio from YouTube.

I can go to Tools-Addons select and disable, but that seems primitive, and a hassle to do repeatedly.
