1) Start Firefox
2) Go to Youtube and play any music video
3) Start new tab and play another music video at same time from Youtube

Expected result:
Media Player widget should show two Firefox tabs with both musics playing

Observed result:
Media Player shows only the second music

4) Pause second music

Expected result:
Media Player should show that first music is still playing

Observed result:
Media Player shows that all playing musics are paused while first music is still playing.

Same behavior can be observed with Plasma Integration extension disabled.

This isn't possible, sadly. Each app can have only one MPRIS data stream at a time. It's a limitation of the protocol itself, as I understand it.
