Most likely, it is an incompatible extension.  If the drive letter 
happens to stay the same between the places that it does work and 
changes on that demo laptop, that would be the issue.  There are a 
number of extensions that are currently incompatible with Portable 
Firefox including GreaseMonkey, CustomizeGoogle and similar extensions 
that save files within your profile.  A later release of the Portable 
Firefox Launcher will fix these incompatibilities.  There is a beta 
launcher that fixes them described here:

Extensions are your most likely culprit.
