What is default the pop up blocker?

A default pop-up blocker is a built-in feature in Web Browsers that automatically prevents pop-up Windows from appearing when a user visits a website. This tool helps enhance the browsing experience by blocking unwanted advertisements and potential security threats. Users can typically customize the settings to allow certain pop-ups for specific sites or disable the blocker entirely. Most modern browsers, such as Chrome, Firefox, and Safari, have this feature enabled by default.
