Microsoft Edge is now giving users the ability to hide those pesky browser notification dialog boxes that are commonly used by web sites to push their content, or even spam, on visitors.

For those not familiar with the term "browser notifications", they are a feature that allows web sites to ask visitors if they would like to sign up to receive notifications of new content. The web sites can then push content to subscribers via the browser, even when a visitor is not on the website or when the browser is not being used.
