bMarks is a web based bookmark/favourites database where your bookmarks follow you from computer to computer. bMarks is designed to be displayed in firefox's sidebar. You can create subfolders which you can share out to other bMarks users and even allow them to add to your bMark folders. bMarks keeps tracks of how many times a link is visited and whether it has resulted in a 404 error et al. Special features include bMarks+ which gives you the oppotunity to add additional info to link url's before you access them - so you can store your favourite website search results and ammend it on the fly. You can also customise the way your bmarks are displayed or even which folder shows up as your root directory - perhaps you would want a folder for work and a folder for home.
