Can't invoke YSlow on Safari? Curious why.

Curious to wonder when this broke, even though looks like the project is abandoned for updates. Safari extension download link doesn't trigger. I assume probably with the recent changes from Apple, the extension isn't hosted from Apple officially and not certified as valid.

And yet falling back to the javascript based method, seems can't bookmark the tool into Safari and mobile Safari. For mobile Safari, can bookmark, but invoking it does nothing. Can't even bookmark on desktop Safari. Maybe Safari is more secure to not allow the javascript bookmark anymore?

Tested on desktop Safari 11.0.2 on Mac High Sierra, and tested on iOS 11.1.1.
