Yay for Foxmarks! It's a free web page bookmark synchronization plug-in service for the Firefox browser.

Install Foxmarks in all of your web browsers (work, home, laptop) and then any time you make a change to your bookmarks on any of them, each of the computers automatically sees the changes when it is next used to access the web.

But wait, there's more: the Foxmarks service allows you to share a folder of bookmarks and is very useful even if you have only one computer and no need to synch bookmarks.

So, for real example: open up a whole bunch of sites (about a research topic of interest) via tabbed windows, save those locations in one bookmark folder with Firefox's normal one-step option to do this, then use Foxmarks to share that folder with anyone via email or RSS.

Sure is easier than composing an email message and copying and pasting in a big list of links!
