I'm not 100% sure if that is how the song is supposed to sound slowed down or not.

It sounds the same on Chrome. So I guess Firefox is doing fine.

Mass change P2 -> P3

I'd like to bump this issue, and note that Chrome? & Safari smooth (resamples?) audio at low playback rates while FF (71.0b9) does not. What can we do on our end to help move a resolution forward?

Reproduced on Windows 10 18363.657, it started happening with the 73.0 Firefox update, I have an older version (portable) that's one Version behind on my USB And this doesn't have the same issue on the same computer, Tried the basic troubleshooting steps refresh profile and such and reinstall, anything I found so far that could be it is bug 1427267 being fixed, Since that went out in 73.0.
