If you are using Netscape 6/7 or Mozilla, you can share your bookmarks with Firefox. All bookmarks are stored in a file called bookmarks.html and is stored in the profile folder. For example, if you want to use the bookmarks for Netscape 7 in Firefox, use about:config to add the String preference browser.bookmarks.file, and set the value to C:\Path To Netscape Profile\bookmarks.html.Replace Path To Netscape Profile with the actual path to your Netscape profile.

This tip can also be used on dual-boot systems to use the same bookmarks on both operating systems. Just make sure that you place the file on a location that you have write access to from operating systems.
