From time to time I'm getting notifications on my desktop from a website I never entered since I started using Ubuntu. Does anyone know how to fix it?

The website I'm getting the notifications from is "Tokyo Otaku Mode". Here is a picture to explain:

If you are using Google Chrome, then go to


Chrome Notifications

and block unwanted notifications.

For Firefox ESR go to Preferences → Content or


then click Choose

Firefox Notifications

and switch unwanted site to Block then Save Changes.

For Firefox Quantum go to Preferences → Privacy & Security then near Notifications click Preferences button and manage them

Firefox Quantum

  • Thank you very much. It is very similar with Firefox too, preference and then I search for notifications. Then I did find the website that was bugging me.

Didn't Stylish have some problems in terms of being an invasive app? Why yes it did, so I'd remove Stylish pronto, if I were you! For reference
