I use Foxmarks to synchronise my Firefox bookmarks across all the computers I use (it also works with IE and Safari now I believe) and it's great. You can create different profiles as well which you can switch between as required, so when I'm at work I use my 'work' profile with access to all my work-related bookmarks. At home I use my 'home' profile which has all my non-work bookmarks. But if I'm working from home as I was today I can easily switch profiles so I have all my work bookmarks at home! This includes all my bookmarklets which is great.
I also use Spped Dial which is a great and highly configurable way of having quick access to my most-visited sites whenever I launch a new window/tab. It's a bit like Chrome's dashboard but you can define which sites you want to show rather than it just displaying whatever you've been looking at a lot recently, which is better I think (the Speed Dial way I mean!).
But working from home today made me think how nice it would be if my Speed Dial 'home page' worked the same way as my bookmarks - so I could switch to my work Speed Dial page instead of my home one. At the moment there is no way to do this (unless there is some clever clogs way of doing it using Dropbox etc.).
Of course, with the steady march of Google towards world domination we'll probably have everything in the browser synced through Google in a couple of years - albeit using Google Chrome....
