Wikipedia Peek is a browser add-on designed for Firefox that enhances the way users interact with Wikipedia. This tool provides instant previews of linked articles, allowing users to view the title section of an article simply by hovering over its link. The pop-up feature ensures that users can quickly access relevant information without navigating away from their current page, making research more efficient and streamlined.

This add-on offers full touch support and comes with four customizable themes: Wikipedia, white, black, and grey/blue. Users can also adjust font size and transparency to suit their preferences. While primarily designed for Firefox, it is also compatible with Chrome and Firefox for Android. The add-on is subscription-based and does not collect user data, ensuring a privacy-focused browsing experience.
