Just to be clear, can you clarify if you're referring to Firefox on mobile app or the desktop one?

@birafa : you may need to explain more what you mean?

If you use Firefox on a laptop or desktop device and you want to prevent a tab from playing sound, you can right-click it and choose "Mute tab".  You can even do that before any sound is playing.

If you mean you want to set a different volume level for each tab, try an extension like this one:
