Oh yea, for sure, I do the same. I especially modify the DOM to get around "lol, no copying into this form field." That's not really the point I'm trying to make though, 99.9% of users don't have the know-how to do this. You pretty much have to be a web developer to be able to use the browser this way.

I agree, although it helps lower the barrier to entry, so that 99% might become 95% or 90%. More than a few times, I showed people a few simple tricks in the Inspector. They felt empowered and it encouraged some of them to continue digging on their own.

Sure, they could install an addon, but that can be very intimidating if they have never done so. If I "wanted to show them a quick trick", I would have already lost their attention completely by the time the addon is installed.
