Sorry for the late response.

I'm afraid that hasn't done the trick. :-(

Doesn't /appear/ to have had any affect, but I haven't rebooted the system yet. I'll get back to you once I get around to rebooting, should the situation change (otherwise, assume it hasn't worked).

> So, do you have any firefox from the regular repository installed or are both, the stable too, from PPA's? Which PPA's? What about Thunderbird? Maybe they aren't built with ATK. I'd like to try them here.

I'm using Firefox *27.0.1+build1-0ubuntu0.13.10.1 (saucy-updates)* from the Ubuntu repositories (universe? partners? I'm not certain which), Thubderbird *1:27.0~b1+build1-0ubuntu0.13.10.1 (saucy)* from the official Thunderbird Beta PPA (ppa:mozillateam/thunderbird-next) and Firefox-Trunk *30.0~a1~hg20140225r170482-0ubuntu1~umd1~saucy* from the official Mozilla Daily PPA (ppa:ubuntu-mozilla-daily/ppa). I also have Thunderbird Daily installed from the latter PPA, but I don't really use it at all.
