Which of the following is NOT a feature of the most popular web browsers? (1 point) Tacked browsing Pinned tabs Session restore Thumbnail preview

To determine which option is NOT a feature of the most popular web browsers, we can analyze each option:

1. Tabbed Browsing: Most modern web browsers, such as Google Chrome, Firefox, and Safari, support tabbed browsing. This feature allows users to open multiple web pages in a single window, making navigation easier.

2. Pinned Tabs: This feature is available in major browsers like Chrome and Firefox. Pinned tabs allow users to keep specific websites readily accessible by pinning them to the browser interface.

3. Session Restore: This is a widely supported feature across browsers that enables users to return to their previous session with all tabs restored if the browser crashes or is restarted.

4. Thumbnail Preview: While some browsers offer a preview of recently visited sites, not every browser implements a "thumbnail preview" feature as defined (for instance, showing a thumbnail view of all open tabs).

Conclusion

Based on the analysis, the option that is NOT universally recognized as a core feature of the most popular web browsers is Thumbnail preview.
