Okay, whilst the addon works perfectly, it seems to introduce annoying adware popups as you navigate around webpages (by which I mean whole screen popups).
I disabled this addon and haven't seen any for the whole day (previously it happened every 5 page changes or so), so I'm guessing this is the cause.
Despite it's great capture abilities, I'm uninstalling it, adware sucks.

Great little addon, working fine for me in FF22 (addon V2.0.2)
