Wikipedia Peek

When you hover a link to another article on Wikipedia.org/Wikia.com or tap on it, a small pop-up will show you the title section of that article.

Features:
* Full touch support
* Load first paragraph and thumbnail
* 4 themes (Wikipedia, white, black, grey/blue)
* Customizable font-size and transparency
* Works in Chrome, Firefox, Opera and Firefox for Android

This add-ons code is available on GitHub (https://github.com/NiklasGollenstede/wikipedia-peek). If you have any problems, please report them there (https://github.com/NiklasGollenstede/wikipedia-peek/issues).

The add-on itself does not collect any data. Note however, that the article previews are queried form the target host in a separate query each time you hover over a link long enough.
