Pearltrees is a different way to share content on the Web. It's a social network and sharing system in and of itself, though it also connects to Facebook and Twitter. Pearltrees lets you "curate" trees or webs of pearls. Those trees are dynamic connections, and you can add, remove, and reconnect pearls (links you find on the Web). Pearltrees are particularly cool as you curate more and more, because you end up with a web of intuitive connections.
The Pearltrees Firefox add-on makes curating Pearltrees a cinch. The add-on inserts three buttons to the left of your browser's address bar: a pearl button that lets you add the page you're browsing to your current tree; a button for choosing where to put your pearl; and a home button that takes you to your Pearltree account.
Note: This link takes you to the add-on's page at Mozilla.org, where you can automatically install the file into your Firefox browser. You will need a Pearltrees account to use this add-on.
