Unofficial YADVASHEM Facebook Chrome Ext. is a free browser add-on developed by Omri Ariav. It is designed to allow users to easily search for Facebook profiles in the Yad Va Shem museum's holocaust names database. The extension encourages users to add their related holocaust victim last name as an alternate name on Facebook.

The extension works by searching for an alternate name in Facebook profiles, and if one is not found, it searches the current last name. It is an open source project, with the source code available on GitHub.

Please note that this extension is not affiliated with Facebook Inc or the Yad Va Shem museum. It is simply an idea by the developer to help commemorate the holocaust in a modern way. Users are encouraged to use the extension and provide suggestions for improvements. For further communication, the developer can be reached on Twitter at @omriariav or via email at
