When I first started using the extension 2 years back, everything was great.

Around late last year, after some update, pressing Play now causes the extension to show the Loading symbol indefinitely. There is no audio playback at all -- until you disable and re-enable the extension. Then everything works until the next time the device hibernates or sleeps. This happens everytime unfailingly.

I reverted to the old version months back and have been using that since, for months, disabling upgrades.

Yesterday, I tried again to upgrade and see if the bug had been fixed but it hasn't. I'll be needing to go back to the old version again, unable to take advantage of the new er features :(

I'm using the very latest Firefox on Windows.
