Notification flag prompts interrupt my browsing flow.

A browser popping up a permission request to ask me whether I want to receive notification is very likely an annoying interruption, and is not relevant to my current task. It would be much better to indicate that the site is notifications-capable with an icon, heck the sites can have an opt-in button, just don't pop up that prompt and force me to acknowledge it.

Go to content settings in both firefox and chrome and you can block all notifications by default.

Well that battle was fought and lost a while ago with the W3C Web Notifications API Standard...
