Beginning in Chrome 70, users will have the choice to restrict extension host access to a custom list of sites, or to configure extensions to require a click to gain access to the current page.
While host permissions have enabled thousands of powerful and creative extension use cases, they have also led to a broad range of misuse - both malicious and unintentional - because they allow extensions to automatically read and change data on websites. Our aim is to improve user transparency and control over when extensions are able to access site data. In subsequent milestones, we’ll continue to optimize the user experience toward this goal while improving usability. If your extension requests host permissions, we encourage you to review our transition guide and begin testing as soon as possible.
