Last night I tried to install Firefox portable on Windows 7 64 bit. Everything worked like normal when I started FF. However, changes made to the settings or add-ons installed are not remembered, no matter whether I run FF as a normal user or with admin privileges.
I can't seem to find anything about this behaviour on the Internet, so I assume that this must be a rather rare issue.
Does anyone have any ideas as to what might be the cause of this problem?
