After few days of researching, I got half of the instruction, looking for Firefox pro to assist. I would like to setup a default firefox profile with bookmarks and homepages for all new domain users when they login into the computer and prevent them to update/modify any of these settings. So far I got the half instruction saying create a "profile" folder from installation path\default folder, and place a bookmarks.html in it, which I have tried, NOT working. Does anyone able to link a video or step by step instruction for me? By the way, replacing files on each existing users profile is NOT what I am looking for, I am aiming for the new users. Thank you all
