Google Chrome extensions to have limited data access, be more private and secure from 2021 Starting in 2021, users will get to determine which websites the extension can access when they browse the web, instead of letting the extension decide. Dec 10, 2020 16:27:52 IST Google Chrome extensions will have limited data access from 2021. Also, there will be a change in how permission works when an extension is installed to make the browser more secure. Google Chrome Product Manager Alexandre Blondin in a blog said that in the coming year, users will get to determine which websites the extension can access when they browse the web, instead of letting the extension decide. Google said that once the user grants an extension the permission to access a website's data that preference can be saved for that particular domain.
