I have tested new Safari on Mojave and Silverlight is not working. Is Silverlight going to be supported?
I have tested Flash and Flash is working properly. I guess Flash is going to be supported but Silverlight not.
Any official statement about this?
There's actually a mention of that in the Relase Notes for Safari Technology Preview, Release 52
https://developer.apple.com/safari/technology-preview/release-notes/#r52
namely "Removed support for running legacy NPAPI plug-ins other than Adobe Flash".
