Is Secondary Screen safe?

Low risk

Secondary Screen lets pages with a meta tag move their popup browser window to a secondary display and fullscreen it.

It injects a content script on every website that checks for a page-controlled meta tag named secondaryscreen shortly after load. If a secondary display has been detected and selected, the background worker accepts the message and uses Chrome window APIs to move the sender tab's popup window to that display and set it fullscreen.
