Firefox sluggishness revisited

[Therem Harth]

So just FYI, if any of you here are being annoyed by how sluggish Firefox is, try disabling the sliding tab animations.

browser.tabs.animate: false

Yes, Firefox has this setting! At least for now. And it makes a huge difference.

(Especially on *BSD, for which current Firefox is just hideous when animations are enabled. But I've noticed the creeping sluggishness on Linux and Windows too.)
