was autoconfig set up on purpose / is this in a controlled enterprise environment?

Chosen Solution

Note that Firefox 10.0.1 is really old (there is a 10.0.2 release and a 10.0.12 ESR)

If she installed Firefox herself then check for the presence of a mozilla.cfg file (or netscape.cfg) in the Firefox installation folder. Otherwise you have to check this with the IT department or the people that provide support for this computer.
