I use Jack and I use Firefox with Jack. It works (mostly) without any problems.
Only when you have really a lot sound related tabs (maybe more than 6 active sound sources or so, Firefox makes new jack channels per tab), Firefox slows down a little bit.

I also very much recommend to use media-sound/cadence together with jack. There is also a version compatible with ladish (a jack session manager) in the audio-overlay [1].

media-sound/jack-rack for example provides certain equalizers.

Best,
Gerion
