Block Website Notification Requests

i prevent localisation to be accessed and it can't be undone ! i spent an hour deleting some preference files of chrome to restore localisation

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".
