Portable Firefox is now compatible with Windows and OSX which means no matter whether you are using somebody's Windows or Mac machine Firefox (and all your preferences) are close at hand. Installation is easy and takes approximately 33meg of your USB key's storage space. I am presuming this value would actually grow over time as your preferences and browser cache grows with use.
I use BookIt 3 for OSX to synchronize all my bookmarks between the different browsers I use. Adding Portable Firefox to this list was easy and everything syncs beautifully. Most of the places I go to these days have Firefox but it is nice to know I have a copy available on my key (with all my useful bookmarks) for those times when you are stuck with only Internet Explorer to cruise the Internet.
