When clicking on an external link in my Facebook feed, the link opens in an in-app browser with a Debug menu in the top left and an FPS indicator in the top right of the page. When I click on the Debug menu I see logs about MetaScreenshotCapture API, IABScreenshotJS module, and IABScreenshotCaptureJSController. When I Google these terms I don’t find anything.
Does anyone know what this is? Should I be concerned?
I am using the Facebook iOS app on an iPhone 14 Pro Max with iOS 26.0. The Facebook app version is “Version 1.0\n531.0.0.35.77 (792629356)”.
