Bookmarks and searching: Instant information access
Many browser add-ons automatically save your bookmarks online and allow you to reach them from any PC, or they synchronize all of your regular bookmarks among multiple systems. Some of the add-ons in this category also introduce better searching or sync your log-on information in multiple browsers--and one even checks for spyware.

Yahoo Toolbar One of this application's many features is the ability to create Web-based bookmarks (separate from your system-based bookmarks) that are accessible from any of your other browsers that have the toolbar installed. The applet also provides quick access to Yahoo Mail and other Yahoo services, and includes a free Norton spyware scanner.
Google Toolbar This program supports Web-based bookmarking, in much the same way that Yahoo Toolbar does.

Google Browser Sync Synchronize your choice of bookmarks, saved passwords, browsing history, and cookies among multiple browsers with this handy application. If you have trouble getting the tool to sync your bookmarks properly (I often did), your best bet is to use this add-on for passwords and cookies and to use Foxmarks for bookmarks.
