If you’re used to working in different departments, you’ll soon find the biggest restriction is that most operating systems are based around multi-user technology and you won’t want to browse personal information, on the web, through someone else’s computer. Sure, you could ask them to set you up with your own account, but if you only want to use their computer for a few minutes, perhaps to check your email, there’s little point.

Mozilla Firefox Portable edition is a transportable version of the popular web browser. You could ‘install’ this to an external USB key and then take this USB key with you, connect to a computer, then use Firefox Portable without leaving any trace of your web use on their machine.

Mozilla Firefox Portable is self-contained software which means that all your browsing history, bookmarks and other cookie information is taken with you, on external USB key. When you browse the web using Firefox Portable, the data is written back to the key. This makes is very useful for taking your own personalised version of the web browser with you, wherever you work or travel.

Note that this is the portable version of Firefox 2.0.0.15
