Script not working
https://www.youtube.com/watch?v=DAsZjMizTJ0

works again?

For me, always not.
1- (v.2.1.3 + Greasmonkey + Firefox Classic v.56.5):
go to the login page...

2 - (v.2.1.3 + Tampermonkey + Firefox Classic v.56.5):
Stay on the video ... but don't do nothing...

But....
3- v.2.1.3 work fine with Firefox Quantum + Tampermonkey:
play the video.

That's a problem of browser or Scripts manager ?

Yeah, now looks like no supported JS functions/API.

Waterfox Classic 2021.04 (aka 56.5) maybe no backported needed new Javascript features.

Can you find a solution about that ?

Note:
I have posted a bug report to waterfox:
[WaterFox Classic] Unsupported JS functions/API ? - (Make an userscript Unusable with Waterfox Classic) #2221

That's strange:
It seems not possible to post a bug report for Classic...

Re tested with Waterfox Classic:
Work fine!
Thanks
