One of the tools I rely on often is Xmarks. Xmarks allows me to sync my favorites between Internet Explorer and Firefox as well as my Firefox passwords between computers.
It is great to be able to have a page open in the office at work when I leave the office for the day, and when I return home open the browser on my home computer and have it open in the same spot.
I never have to worry about not having a saved password to favorite as well.
If you currently do not have a tool to sync favorites between browsers and computers as well as passwords you might give Xmarks a shot.
