That's the beauty of Delicious. They save your bookmarks as tags on their computer. So you just sign in to delicious from any computer in the world that has Firefox installed with the delicious plugin and you have access to all your tagged bookmarks and can easily generate a toolbar filtered to any tag.
You should try it out.
Ditto that. I have several computers "Xmarked." Also Adblock Plus. Those two additions go on every machine running FF.I like Chrome, too, but I'm in FF 99% of the time.
For those anti-google people on this thread, go into your tools/options/security tab and unclick the "suspected attack site" and "suspected forgery" boxes. These call google everytime you click a link. This will speed up your Firefox a bunch.
Mine too. And Speed dial. No addons, no Chrome.
