Actually, it's not about copyrights or intellectual property or anything like that. If anyone copyrighted something and didn't want people to nick it, the
last thing he'd do is post it up on the internet
What I meant was, Internet Explorer blindly accepts all commands given to it. If a script running on a page says "Oi you, add this stupid web page to your bookmark, install this spyway and pornography dialer, and throw in a blue screen of death while you're at it", IE will do exactly that. So in this case, the script is saying "Hey IE old buddy old pal, i don't want you to be able to select this text, because then you might copy it and paste it somewhere", and Explorer says "okay :sob:"
Mozilla, on the other hand, will say "Hold on just a second here. You're just a bloody web page, I'm the one who gets the final say and decides what
I show and what scripts
I run. So you're gonna give me a suggestion, like "Hey Moz, why don't you not select this text", and me and my partner salilah will sort out whether we want to give you this kind of control or not".
