Ubuntu :: Privacy And Firefox ?

I remember that one complaint about XP was the way that when you used Firefox or IE index.dat files were created which were violations of privacy.

If, after browsing, one deletes the relevant firefox files are there any other locations or logs in Ubuntu that record details or times of browsing?

Currently these files seem to contain browsing history:

I have looked in the /var/log directory and cannot see anything but perhaps other people know?

I just want to know if and where browsing activity is located (apart from in the /user/.mozilla directory).
