Is Marqly: Bookmark Manager, New Tab & Highlighter safe?

Marqly lets any HTTPS page trigger visible-tab screenshots through its video detection bridge.

Marqly injects a video-detection bridge into HTTPS pages that accepts page messages and forwards them to the extension service worker. A page can use that path to make the extension capture the visible tab and render the resulting screenshot data URL in an open shadow DOM, where page script can read it. The same bridge can also make the service worker fetch attacker-chosen video URLs from extension context for size checks.
