> disabling Ublock origin via the extension doesn't solve the issue I can't reproduce this on my side, disabling uBO on `https://www.freenews.fr/` makes the "Save As..." error disappear. Also, uBO does not use `parentFrameId` when `tabId` is `-1`. uBO's logger should be used to validate that uBO didn't block anything as "Save As..." time after being disabled. If the logger does not show anything being blocked, it must be investigated that something else than uBO blocked network requests.
