It seems that there's something funky with the Session Catalog such that
Firefox doesn't seem to like it - even though it says there are sessions
(i.e. there are numbers after Sessions and Speakers) none are listed,
with or without any filters. The loading icon spins when the page is
visited but nothing is then shown.

I've seen this with Firefox ESR 52.2.0 on openSUSE Leap 42.2 and Mobile
Firefox on an Android tablet - it's at home and I'm not right now so I
can't give versions.

It doesn't seem to make any difference whether logged in to Session
Catalog or not.

Things work as expected with Chromium and Chrome on openSUSE and Android
respectively.

Hmm just before I hit Send I disabled the uBlock Origin plugin that I
use with both Firefox instances and after refreshing I can see the
sessions listed. Okay so there's something that uBlock Origin doesn't
like ... will dig further.

HTH.
