Backup and Synchronize your Bookmarks with Dropbox

Dropbox is a great application for keeping your bookmarks of iceweasel ( or firefox ) at a safe spot.
Type in your URL bar about:config and search for browser.bookmarks.autoExportHTML . Doubleclick it so that the Value will become true. Now close iceweasel ( firefox ) and go to your profile folder ( check ~/.mozilla/firefox ). The profile folder xxxxxxxx.default  is the profile folder name for the default profile, where xxxxxxxx represents a random string of characters. There you will find a file bookmarks.html. Move this file to your Dropbox folder and create a softlink back to your profile folder. Everytime iceweasel ( firefox ) is closed the most recent bookmarks.html will be written to your Dropbox folder...
