skoniks Extension scripts in execution world 'MAIN' have empty window.chrome and window.browser, so no of ChromeAPI is working like chrome.runtime.sendMessage throws an Error. All was working about a week ago.
skoniks I think it is the same problem as here https://orionfeedback.org/d/11848-extension-background-requests-doesnt-work
skoniks I used eruda to add debug tools and show context from console, but the same problem can be tested by window.alert(chrome); window.alert(window.chrome); response - empty object;
