Google has not added an option to the Chrome settings to turn off the feature. This may happen in the future, but Google has not commented on this yet.
For now, it is possible to turn the feature on or off using an experimental flag.
Here is how that is done:
- Load chrome://flags/#top-chrome-toasts in the Chrome address bar.
- Change the status of Top Chrome Toasts from Default to one of the following options:
- Enabled -- enables the feature (this may not work for everyone)
- Enabled with 8s, 10s, 12s -- enables the feature and sets the toast period to 8, 10 or 12 seconds.
- Disabled -- this turns the Toast feature off.
- Restart Google Chrome.
To disable the Toast popups, set the value of the flag to Disabled. This turns it off.
Note: Google may remove experimental features without prior notice at any time. The option to disable the Toast notifications may be removed in a future version of the browser.
