If Google’s Chrome notifications have been annoying you like everyone else you’ve probably disabled them. But after a recent update they have come back for me, and the Enable Rich Notifications option is no longer there. They have just renamed the feature. This is an updated tutorial on how to disable the Google Now Notifications inside Chrome.
1. Open Chrome and type Chrome://flags
2. Press CTRL+F and search for Enabled Synced Notifications and Enable Google Now notifications support.
3. Change the setting from Default to Disabled.
4. Close Chrome and open it again.
