Google will block Chrome add-ons from third-party sites

Google has instituted a new rule that should keep Chrome users safe from malicious add-ons: starting with version 21.0.1180.41 (currently in beta), the browser will block all third-party extensions, apps, and user scripts that are not hosted on the Chrome Web Store.

The move is aimed at preventing the all-too-popular attacks mounted through booby-trapped websites that automatically trigger the installation of malicious extensions. These extensions often keep tabs on what pages the user is visiting.

Google is looking to check all third-party extensions that are submitted to the Chrome Web Store for signs of malicious functionality.

The inline install option that allows third-party extensions hosted in the store to be downloaded through the developer’s own website will still be available.
