I am looking for tech advice on setting up filters on my laptop to prevent myself from accessing porn sites. Do I need to change browser settings, must I install software or is it a combination of both? If it's a case of installing software, what is the recommended software? Will this filter out all pornographic content or do I need to specify particular sites/URLs? Does it require setting a password and is there any way to set a password in such a way as I can't break it when I get the urge? If someone else uses my laptop, will it be apparent to them that I have filtering software installed? All advice appreciated.
