Квадратный ВКонтакте is a free Chrome add-on developed by Anton Bakhirev. It is designed to bring back square user avatars on the VKontakte (VK) social networking site.

With Квадратный ВКонтакте, users can enjoy the classic square avatar style that was popular on VKontakte before the introduction of rounded avatars. This add-on overrides the default avatar display settings and replaces the rounded avatars with square ones.

By installing Квадратный ВКонтакте, users can personalize their VKontakte experience and bring back the nostalgic square avatars that they may prefer. This add-on is a great option for those who miss the square avatars and want to customize their VKontakte profile.

Please note that Квадратный ВКонтакте is only available for the Chrome browser. It falls under the category of Browsers and the subcategory of Add-ons & Tools.
