SYBU JavaScript Blocker – Release and Version history

September 2022. We have temporarily removed the extension from the Chrome Store due to performance issues. Google’s enforcement of Manifest V3 requires significant changes on how an extension can block requested resources. If you have the extension enabled and set to My Rules and this is causing slow page requests, then consider disabling the extension. We are working on an update.
