control: severity -1 minor control: forwarded -1 http://crbug.com/473958 control: retitle -1 chromium: pdf and two factor extensions can't be removed
Upstream intentionally builds these extensions in by default. In fact upstream hides them by default. If you don't want to see them in the debian extensions list, you can remove --show-component-extension-options from chromium's command line options. Best wishes, Mike
