Clicking on menu option to create a screenshot causes current Firefox tab to crash.

I found a workaround: using window.wrappedJSObject instead of plain window.

The workaround creates new problems and isn't very handy – it causes problems with messaging between windows via postMessage – responding with e.source.postMessage from popup window to the main window (e.source) fails.

The same issue occurs inside private browsing windows, without any "container add-ons".
