Today, I reinstalled the Xmarks Firefox add-on. It is a very easy to use add-on that creates an easy method for syncing all of your bookmarks on all of your computers (assuming they have Firefox installed). My purpose for the add-on is to keep my laptops bookmarks in-sync with my regularly used home desktop computer. With all of my college and work being online, I am constantly adding bookmarks and since I only use my laptop a small percentage of the week, compared to my desktop, it is an annoyance to try and find and duplicate the bookmarks to my laptop. Xmark is probably the best solution out there for solving this type of problem.

UPDATE: Along with Firefox (as always), Xmarks is available for Chrome, IE, and Safari.
Status (as of Oct 14, 2009):
Chrome – open alpha
IE – full support
Safari – full support

Other possible uses

• Family Computers: If your like my family and every member has their own computer, you may find it useful to synchronize everyone’s bookmarks. Since I don’t have a printer hooked up locally to my computer, I am constantly using my siblings computer for all of my print-jobs. Xmarks has a feature that really makes this interesting. The feature  I’m taking about is the use of profiles. In the example of family computers, you could create individual profiles for everyone, that way when they go to any computer, they just change Xmarks to use their profile and instantly they have their bookmarks loaded.
• Password Sync: Along with syncing your bookmarks, the add-on can sync your saved passwords securely between your systems.
• Project Collaboration: Sync a folder of bookmarks between your project members, that way they’re constantly on your computer. This practice can save you time by keeping you from having to look through chat logs, trying to find that one stupid link. (btw, the instant messenger Gtalk has a great chat log search feature)
