I'm running some research on how people search the web for specific types of information.
I'd like to be able to set them up with a laptop and browser and then record a history of what they search for and what sites they visit.
A Firefox or Chrome plugin would be ideal, but a standalone program is fine too. It doesn't need to be free, just quick and reliable.
It doesn't need to be a general PC monitoring program (though that would be OK too) - it's only Web usage I need to track.
I've found a few on the Web but am not sure which ones to trust. Your recommendations would be much appreciated.
