For what it's worth, Chrome tells you which tab audio is playing from, it's nice.

I think Chrome is able to do this because it separates tabs into processes, but I don't think there's a good way for Firefox to do it since everything is in a single process.

I don't think this has to do with multiprocess. The instance of HTML engine (geckk?) just needs to track who used the audio API.

I think the problem with that is it doesn't work with Flash audio. With multiprocess browsers, the Flash audio can be associated with a tab, but that's awkward/not possible if everything is in the same process.

Chrome didn't have this feature for a very long time, and if anything sounded like it was actually harder because of how Chrome handles their processes.

Well, Chrome still often shares the same process for groups of tabs. I think this particular feature has something more to do with a change they made to their plugin API.

Now if only Chrome had a mute button in the same spot to shut it up.
