Re: [LAU] html5 in ff through jack

Hi Robin, dear list,

I am taking up this old thread from more than a year ago. I am wondering
what the status of html5 audio through jack in the firefox browser is on
Linux?

Debian lists the following versions for the firefox-esr package:
52.4.0esr-1~deb9u1 for stable
and
52.4.0esr-2 for testing

Both packages do not seem to rely on libjack, so I suppose no jack
support in there for now?

Does anyone know more?

thanks!
P
