Wikipedia Anywhere автор Ray

This extension allows you to access the mobile version of Wikipedia on any webpage. To activate the extension select a text and then press the "W" icon. To hide the panel, select anywhere outside the panel.

Note that to improve the loading speed, the mobile version of Wikipedia is loaded inside the panel. You can change this from the options page.

Size of the panel as well as the bubble's position is customizable. You can also change the default "en" locale ( the language of the loaded Wikipedia page) from the options page.
