If support doesn't work for a website, please tell us what that website is. While we try our best to support as many sites as possible, we depend on community submissions to add site support and let us know when sites have updated in a way that breaks our functionality. Without specific information about what sites you think don't work, we can't improve support.

As far as harvesting data, what you said is objectively false. The full source code is available at https://sourceforge.net/p/cookie-cutter/code/ci/master/tree/ and this addon has NEVER collected any data. It doesn't make ANY network calls. Don't make false accusations.
