Looking for a good online bookmarking site

Hi guys, long time no see! I've been working from several different computers recently and missing the bookmarks on my home computer. I know there are sites out there that will store your bookmarks online so you can access them anywhere, but does anyone have suggestions of which one is the best/safest?

I've considered going through google toolbar, but I'm assuming that I'd then need google toolbar on every computer I'm working on and that's not an option. Is my assumption correct?

I've also looked at MyBookmarks.com, but there isn't much info on how it works. Am I going to be downloading something? How does it export the bookmarks, etc.

Is there something else out there that's great (and free) that I just haven't come across yet?

So, I turn to you, my dear geeks. Thanks for any advice you can give.
