Still does not work on this page: http://www.siliconrus.com/2014/01/37signals-benefits/ When Clipper is disabled, no error in Web Console, but when it is enabled a lot of JS errors are shown. Looks like it conflicts with some Facebook JS: These messages are shown only after reloading the page. Subsequent clicks do not change anything and nothing is happening. Sometimes these error messages are also shown on page reload: OS X version: 10.9.1 Safari version: 7.0.1 Clipper version: 220.127.116.11 (latest test build from this thread). Thanks.
