I had a few sites send me notifications for interesting articles with Chrome. Just like any app I would get a notification on my phone for the app event, in this case an article on that site, so if I clicked it it'd take me to Chrome and directly to that site and the article. After switching to Firefox I went to those sites and signed up for notifications. But when I get the notification and click it all it does is open Firefox. It never takes me to any of the corresponding sites or the articles. It's very frustrating.
