zap-hud: daemon mode always crashes

I think that this may be due to something wrong with Firefox - but the error output is a little mysterious. If I don’t use -daemon then it works (but I have to click through the GUI manually, and I MUST use chrome).

Is there a secret command for choosing to launch a different browser? using -browser chrome makes it hang…
