Could you please make the extension also toggle dom.popup_maximum to 0 on top of clearing dom.popup_allowed_events? Without dom.popup_maximum set to zero some popups are still able to get past but with it also set to zero absolutely no popups are able to bypass this. I had previously modified this extension myself to do this but now that Firefox Quantuam is out my old modified version doesn't work anymore. If you could do this the extension would then be perfect 5/5. Thanks.
