Firefox oddness

At home, I can no longer use the Tabbrowser Extensions - it causes all sorts of problems, even if I religiously keep installing the latest version, and I have to rely on about five other extensions to do what it does (and even then, there isn't a proper tab scroll bar). But the history is ordered by day, at least for the past week.

(If someone knows what to tweak to get it to sort by date for longer than that, please let me know!)

At work, the Tabbrowser Extensions work wonderfully. But the history isn't arranged by date.

Weird.
