Livre d'Or

I'm currently running Ubuntu but with XFCE on top instead of Unity - no flashy special effects, fortunately, but it's still part of the Ubuntu Massif. I'd recommend it, if you're happy with Ubuntu aside from the flashiness. Also, I believe it runs Steam now!

Anyway! I actually came to comment on the Firefox settings thing. Firefox has a built-in sync now (in the options / preferences menu) which allows you to back-up and share settings between multiple machines. The first time you do it, it backs you up somewhere online, and subsequently any connected machine you use will download any changes you've made since you last used it, and upload any changes you make while you're on it.

It's slightly easier to get set up initially when you have both machines in the same place, but you can absolutely do it remotely. I've been using it since it was introduced (and similar add-ons before that) and it's brilliant - it can sync your bookmarks, history, add-ons, passwords, preferences and tabs. I've just moved work computers, and the tabs and preferences didn't all come across, but I'm not sure whether I'd ticked the boxes on the previous computer to specify that, but the rest are all working fine. I use it at home, for my desktop and netbook, and at work, when I'm moving between computers and also for the work account I have on my netbook.

Definitely worth setting up even if you only ever use a single machine, in my opinion, but ideal if you're multiply computered.
