SiteBar!
Always want to have access to your bookmarks? SiteBar is the solution. I’ve been using it on and off and am quite satisfied. It is possible to store several bookmark collections and do so securely. All is stored in an sql database. Firefox has a plugin/extension which eases use. For more info look at the SiteBar website. Wanna use it? Contact me and I’ll set up the server side part for ya.
