Hello, thank you for taking the time to check this out.

I was closing the volume mixer after I no longer needed it and realized that Firefox was showing levels go up whenever I spoke into my microphone. I had been using it before to chat, but not on Firefox at all during the session at the time. No music or videos were playing in any of my tabs. After a while, it no longer picked it up, but I know for certain that there was no output of sound coming from my computer. I haven't been able to replicate it yet, but it does worry me.
