Is there any way that I can restrict people from going on to certain websites using Mozilla Firefox, my brother has been selling my stuff on eBay, so I don't want to allow him to access it at all, as he's really annoying my parents aswell... he sold something for £3 that could've been sold for around £50... how naive... It would help if you knew how to do it in internet explorer aswell
... any help would be appreciated.
