Sorry, but I have to say that I cannot make much sense of your request, aside the fact that it is not for either Netscape or Mozilla, which are handled at this newsgroup. You post should belong at the Communicator group.
But, I would prefer to put this one to sleep, because it is not connected with any particular problem.
But, you are concentrating on the the liprefs.js file, and no other file in that directory. You said that the computer place was closed, but was the computer in your hands by then. In other word, you dropped off on Saturday. Did you pick it up the same day?
My liprefs.js file has 55 entries, and was not touched since May11, which tells me nothing. Many, if not all of the lines are duplicates of the prefs.js file.
But, I got this from a page in a page which I got from a search. By the why one item mentions that liprefs.js file is for Macs, but none of the others do.
<BTW, if you're really paranoid about your privacy, there are a couple more things you may wish to do. If you don't want a history of websites you've visited to be saved onto your hard drive, you can also make the files: PREFS.JS, LIPREFS.JS, and NETSCAPE.HST read-only (also in your user's directory). This will completely prevent any future "history" to be written to disk. To clear out your existing "history", delete the NETSCAPE.HST file then open Netscape. Netscape will recreate a new (clean) one. You can also use any text editor to open the PREFS.JS and LIPREFS.JS and delete entries such as user_pref("browser.url_history.URL_1", "http://www.knowplace.org);. After you're done editing, make sure you remember to make those three files read-only.>
and, you can download Adaware from

I found it to be good, but may be too much for any impressionable person. I went through a period like that, and I ended up deleting, instead of just quanrantining a file necessary to drive one of my programs.
