Install Xmarks on each computer you use, and it seamlessly integrates with your web browser and keeps your bookmarks safely backed up and in sync.
Xmarks will sync across browsers too. Today we support Firefox, Chrome, Internet Explorer, and Safari (Mac OS).
While we’re in the same sort of area:Delicious.com does a similar sort of thing, letting you store and tag bookmarks with browser extension or bookmarklets. You can also get access to them on the go, eg. http://delicious.com/damncabbage (You can make links private, and they won’t show up here.)The killer feature, though, is the ability to search everyone else’s public links; it’s like a giant, curated version of google, with results pre-screened and tagged by everyone else bookmarking interesting or useful things as they find them.(It’s a damn shame that Yahoo! hasn’t done anything with it since they acquired it; Yahoo! Search could’ve really used the help, but now that’s gone to Bing.)
