[xubuntu-users] How to stop firefox 'pulsing' its panel tab when a new site opens?

[Chris Green]

I find it very annoying when Firefox pulses its tab in the panel just
because I have opened a new site but haven't yet moved to Firefox to
display it.

I *know* I've opened a new web site and don't need the distracting
panel pulsing to tell me.  It also happens when Firefox restarts and
restores what was showing before, even sillier in this case as there's
nothing new being shown.

So - is it possible to disable this behaviour?
