location.href="javascript:Function(); isn't working for Firefox extensions

问题

In Chrome web-browser extensions I can use the next method for calling/triggering a web-site's (page) js function:

location.href="javascript:SomeFunction(); void 0";

It works great.

But it doesn't work for Firefox

Though in old Firefox addons I could call web-site's js functions in similar way like this:

var wm = Components.classes["@mozilla.org/appshell/window-mediator;1"]
                  .getService(Components.interfaces.nsIWindowMediator);
var mainWindow = wm.getMostRecentWindow("navigator:browser");
mainWindow.gBrowser.loadURI("javascript:SomeFunction(); void 0");

But now it's all about Firefox Web Extensions and I wanted location.href="javascript:SomeFunction(); void 0"; to be working in FF
