Google Search Language Changer 作者： OmerFI

Google Search Language Changer is an extension that allows you to quickly change your Google Search language preferences such as pages in the specified language and web interface language.

Only available in English and Turkish for now.

Explanation:
This extension is NOT a TRANSLATION extension.
Let's say you want to search Python Wikipedia on Google. The results will appear in your native language. This extension allows you to switch languages so you can search for the same content in different languages.
