Are you calling a custom mouse icon crap/fuckery that makes you leave the site, or was there something I missed? If you are that's a pretty big overreaction. And it's probably worth you setting the single line to disable `cursor` on all sites via userContent.css or a styling extension.

It has been a while (I think ever since Safari introduced Reader Mode), and I do almost all my reading on websites in Reader Mode. For some websites, I have set to “Use Reader Mode when Available,” such as that of paulgraham.com, daringfireball.net, and quite a few others with horrible Typography.

You can turn it off, there's a little toggle at the bottom of the page.
