TBF, a lot of people used to keep portable apps like this... then IT started locking down even being able to mount a USB storage device. I used to do this for my email and mail profile with a portable Thunderbird.

I even worked on an app in a relatively secure environment where the work around for an early SPA and IE6-8 company wide, was for the systems analysts using our app to use a portable firefox browser on the user desktop. IE6-8 in particular were really bad when you had an SPA as you had events tied to dom elements across the COM bridge that wouldn't release unless all dom and script references were freed up. jQuery actually did this, if you managed everything through it, but our app was an early version of extjs... so after 3-4 hours it would just run out of memory and die.
