From Arin Waichulis at 9to5 Mac, this is worth a read.
I had never heard of StopTheMadness, which is not cheap (as you have to buy Mac and Mobile versions at $7.99 each) and the Mac version also works on Firefox and Chrome as well. It overrides websites attempts to lock out browser features, which is something I have been thinking about for a long time. It can also remove tracking tags, and URL shorteners.
