Google Chrome is one of the world’s most popular web browsers currently in use. It is fast, powerful and can be customized with tens of thousands of extensions that enhance its functionality.

Google Chrome is frequently updated, which can make extensions obsolete. In addition, various incompatibilities can cause extensions to fail under load.

However, many users have reported encountering an extension-related error message when using Google Chrome.
