Tools that prevent unwanted pop-up windows from appearing in web browsers.

• A. Pop-up blockers
• B. Password management
• C. Accessibility
• D. Appearance

Answer: (A)

Blocking unwanted pop-up windows in browsers is being tested. Pop-up blockers monitor when websites try to open new windows or tabs and stop them from appearing, usually by preventing automatic window.open calls or by suppressing the new window while still allowing user-initiated actions. They reduce interruptions, protect against some deceptive prompts, and can speed up browsing by avoiding unnecessary windows. You can usually configure them to allow pop-ups from trusted sites if needed. The other options don’t address this issue: password management handles credentials, accessibility improves usability for all users, and appearance changes the browser’s look—none of these prevent pop-ups.
