A word of caution, some of these settings break stuff.

I don't remember the exact items anymore, but seemingly innocous privacy-related changes I did some time ago from a list very much like this broke the ability to paste to google docs (which was a bit confusing, since I noticed it weeks later when it "just" didn't work with no messages hinting why) and the integration for the Evernote WebClipper plugin; and it was a bit of a hassle to find which changes I need to revert.
