// turn off application updates:
   user_pref("app.update.enabled", false);  "

From the thread number above > "Here's how I do it. http://kb.mozillazine.org/User.js_file The file has to be named user.js and it has to be located in the active Profile folder. And this is the correct code for disabling updates. // turn off application updates: user_pref("app.update.enabled", false); " That may sound very simple to some, but it raises questions in my mind. What is the path to the active profile folder? What is the exact name of said folder? Do you add those two lines to what is in there or do you replace lines with this? You make sure it only says that and nothing else in the file? I'm not a programmer (Clearly) and I dont want to be. I would love to read a complete explanation in standard English where the writer assumes I know nothing except English. No assumptions and no ambiguity! Please explain it to me like I was five if possible. I certainly know how to create a text file. I know how to find files, unhide system files and a good working knowledge of using the path (when given to me). Is this kept in program files or app data? As for the continual harangue about security, I believe that update does not equal improvement. Very often I find it limits our ability and program utility. Only the extremely naive would believe newer is better in every way. It's not. I've seen too many user rights disappear in the name of security, when in fact they were in the service of copyright protections for content providers, not our protection. Just ask the NEW CEO and compare the release right after he took over with the prior release. All of a sudden every download utility stops working. My "security"... Using 38.0.5 on Win 7 Professional (64 bit) and I wish to keep it that way. Thank you very much for your kind and complete replies.
