Hailing to all Firefox 1.5.0.X users, please update your Firefox to the latest build, Firefox 2. Though there was a recent update to Firefox 1.5.0.8, but Mozilla has posted in it's website that it would halt updates for this version in April 2007.

Clipmark is a bookmarking tool extension for our dearly Firefox. But Clipmark has a different approach to bookmarking which is rather cool in my opinion. Using Clipmark, you could bookmark only the important parts of a web page, such as a couple of paragraph from a text or some beautiful images that you found in someone's online Photo Album. Unfortunately, Clipmark doesn't support bookmarking videos, though it would be better if it does.
