# Known problems {#known-problems}

-   Screenshots need HTTPS and a browser with screen capture
    (`getDisplayMedia()`). Without it the dialog works, but without a
    screenshot.
-   The extension is tested in Chrome. Firefox and Safari are not tested yet.
-   Drawing markings on the screenshot needs a pointer (mouse, pen or touch);
    all other controls work with the keyboard.
-   Images on the page and the document size are only part of the admin panel
    details when the page was rendered without cache.
