Because of that you cannot use Safari to uninstall it. It chokes Safari every time I try to install it. This version of JS Blocker (5.0.19) is a total disaster. To stop this inexplicable popup warning, uninstall JS Blocker from your extensions. The old Gallery is being deprecated in favor of the a App Store equivalent anyway. Apparently, Apple hasn't yet cleaned out its Gallery of blocked extensions. An error occurred while installing the extension 'JS Blocker 5'.', what's going on is Safari attempting to inexplicably install the remaining version of JS Blocker in the now legacy Safari extensions Gallery. Sorry about this, but there's nothing I can do.'īTW: If Safari give you a popup warning saying 'Safari can't install this extension. JSB will never work again going forward unless Apple reverses this decision.
'Apple has dropped support for what they deem 'legacy extensions'. If Apple does in the future allow for extensions like JS Blocker, I will be very grateful.
JS Blocker was brilliant, incredibly useful and relatively easy to use. It no longer works with Safari and will not be updated to fit into Apple's requirements. JS Blocker is IMHO the most unfortunate casualty. Unfortunately, not all of Apple's choices in blocked extensions made sense. Apple's goal was to increase Safari security. Safari 12.0 radically changed its extension system.
