When you run the installer for thunderbird it extracts a number of files and puts them somewhere, where does it put them? The machines I want to install thunderbird to can only run things from certain directories (which excludes the users home directory), as a sys admin I want to be able to install thunderbird, but I cant as it appears to extract files to some directory where we cant run applications from. Ideally I would like to be able to move the files to somewhere where they can be run (as changing the security policy will take weeks if I am lucky).
