Its just works! I think its really a pain to enter in configuration and disable permision to sites to send notification. I think its an abusive policy that should be unnalowed by default by google, but yeah, money. Thanks, really!

This extension needs an Allowed Sites list. I want to block notifications on 99% of websites, but this extension prevents notifications from the 1% I want, which makes this extension useless because it has to be disabled. I ended up uninstalling this extension and going with the paid extension "Pop up blocker for Chrome".

לא עובד.
