If happens so very often when you are reading something on Wikipedia you need to open up another article to better understand the one you’re reading. You open up Wikipedia to learn about one thing, and end up following a trail of links just to try and understand the first thing you opened. You don’t necessarily need to read the entirety of every article it links to, you just need a general idea of what a specific term means so you can better understand what you’re reading.
Wikipreview (free, chorme) saves you from opening them in tabs by showing you a preview of that article. Wikipreview solves this problem by previewing articles when you mouse over their link in Wikipedia. The length of the snippet can vary from 420 to over 700 characters but is restricted to the first paragraph. Links in the snippet are clickable but the extension does not give preview of links inside a preview. This will help you minimize the tab-opening you need to get through a specific article.
