Great job!
It "fixes" Google's veto on background YouTube playing.
Thanks so muuuch

Brilliant

Minimize Firefox while it plays the YouTube video & perform other tasks on three phone & Firefox continues to play the video in the background. Also the same when Your switch off the phone ... Firefox will continue to play it in the background. This used to be a normal feature of Firefox until a few months ago when it was removed with updates to the App. Thanks to this extension by Timothy Chien,we have the fracture back.

Good nice great job
