Notifications on Google Chrome are basically dead... well, at least the ones the browser itself generates. A while ago, the company made an effort to join its notifications with the user's OS-bound notification center and, depending on how you've set that up (or not), that can end up being more annoying to deal with. Fortunately, there's a way to bypass that nonsense!
One more noteworthy feature snuck its way into Chrome 86. It's a small change, but it should help make a further dent in the growing problem of notification abuse. In this latest release, sites known for abusive notification content (things like distributing malware or falsely scaring users with fake system messages) will get the same silent treatment as sites that try to trick users into enabling notifications.
Chrome notifications, while useful for a handful of things such as messaging, are generally just an annoyance — the pop-ups requesting permission to send them are grating in the extreme, and the answer is almost always "no." Google, evidently aware of this, has been flirting with hiding them automatically for a while now, and in Chrome 80, that'll be the default behavior for most users.
Chrome notifications are great in theory, but now that virtually every site supports them, that constant, nagging banner under the URL bar can get annoying fairly quickly. Of course, you can always block each site individually, but that doesn't really solve the issue, since you'll still get the pop-up every time you visit a new site that supports Chrome's notifications.
