Sorry, need to remember slang is not very handy in these types of
context... :facepalmingmyself:

By going bananas i mean going overload. It doesn't push a full 100% over
longer periods of time, but the task manager shows firefox eating
between 95% and 100% of resources. also the sound starts flickering.

I use the java script to control audio objects on my homepage a pretty
simple pause/play button, with an eventlistener loading new url when
sound ends.

This happened to me as i was developing it using jekyll's build in http
server, and hence while i was refreshing a lot and frequently.

I can reproduce it on many other pages with audio tags. Not only my own.
Everytime i refresh such a page, a new playback item for firefox is
displayed in the pulseaudio Volume Control, while the old ones remain
althought the VU meter is inactive on the older ones. If i quit firefox
these items disappear, but closing the concerned tab will not help.

Hope this clears it up. If you have any idea of what else i can test,
let me know :)

Thanks again!
