*******************************************************************
Update 4-14-18
We are still working on the new version of CYS, it has not been abandoned. We are not responding to tech support emails at this time. Please be patient, thanks.
Update 10-17-17
There will be no more updates after v5.7.36. We are rewriting the code from scratch, not just for WebExtensions but for the other browsers as well. We will be back soon with a new and improved version of CYS.
There will be no more tech support until the new version is out.
