It does what it's supposed to do.

Adds the option to right-click. Neat, unobtrusive.

Отличное расширение для Mozilla Firefox: простое, с русским языком. Только то, что нужно, ничего лишнего.

There are two other similar add-ons available on the Firefox extensions webpage, but "Search with Wikipedia" is the only one that is compatible with the Wikiwand add-on.

Done

Total fail. Don't download this rubbish.
The language option doesn't work, and that mean the whole add-on become usefulness, because you can't search in different languages.
For example I choose Russian in options, and then search some russian word but get result in a different chaotic strange language.
