delete private data in FF
I have an Asus (linux) which I borrowed from a friend, and I now need to return it.
I am trying in FireFox to delete all browsing history, but it doesnt seem to work.
Clear Private Data (then I check all boxes)
(then I click the button "CLear private data now")
However, absolutely nothing happens! Can it be so that the admin has disabled clearing of private data, and if that is the case, how can I enable the option to clear private data again?
Where are all the cookies, temp internet files etc saved, maybe I could delete them directly instead of using FF?
