the `target="_blank"` attribute opens a linked url in a new browser tab (not a separate window) by default—though user browser settings or extensions may influence whether it appears as a tab or window.

In modern web browsers—including Chrome, Firefox, Safari, and Edge—<a href="https://example.com" target="_blank">Link</a> almost always opens in a new tab, not a new window. This behavior is standardized across desktop browsers and reflects current UX conventions: tabs are lightweight, efficient, and integrated into the browser’s interface, whereas pop-up windows require more system resources and are often blocked or discouraged.

Here’s a minimal working example you can test right away:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Target Blank Demo</title>
</head>
<body>
  <p>Click the link below:</p>
  <a href="https://developer.mozilla.org" target="_blank">Open MDN Web Docs in a new tab</a>
</body>
</html>

✅ Save this as index.html, then double-click the file to open it in your default browser—or drag it into an open browser window. Click the link: it will open in a new tab.

⚠️ Important notes:

• It’s not up to the developer to force a “window” vs. “tab”—that decision lies with the browser and user preferences (e.g., some browsers allow users to configure _blank to open in a window, but this is rare and non-standard).
• Always pair target="_blank" with rel="noopener noreferrer" for security and performance:

  <a href="https://example.com" target="_blank" rel="noopener noreferrer">Safe external link</a>

  Omitting rel="noopener" can expose your site to security risks (like window.opener access) and hurt performance (the new tab inherits the original page’s process).

? Pro tip: You can force a true popup window using JavaScript (window.open()), but that’s fundamentally different from target="_blank" and subject to aggressive popup blockers. For standard navigation, _blank means “new browsing context”—and today, that context is virtually always a tab.

In summary: target="_blank" opens links in a new tab by default and by design—no ambiguity, no inconsistency across compliant browsers. Focus on using it safely and semantically, and let the browser handle the presentation.
