I thought I would try moving my profile out of the way to see if performance

directory isn't the way to go.

You have to have the profile directory there otherwise Firefox can't
check if it is open already.
Try something like
~.mozilla/firefox $ for i in *.default ; do mv $i OLD.$i; mkdir $i; done
And you can open Firefox with a clean profile.

Alternatively,
~.mozilla/firefox $ mv profiles.ini OLD.profiles.ini
And then Firefox will think it is being opened for the first time.

Concerning the slowness being gone, maybe it was just luck?

IMHO it was the restart that "fixed" it. I experience this "getting slow" think to happen for a long time. After several days of run, firefox needs to be restarted. 1. it's taking too much RAM, 2. usually causing higher CPU load than after restart with same tabs and history open. BTW: same I have to do with gnome-shell, so maybe some graphics card driver is leaking.
