// https://github.com/gorhill/uBlock/issues/1004
// Merely READING the `gBrowser` property causes the issue -- no
// need to even use its returned value... This really should be fixed
// in the browser.
// Meanwhile, the workaround is to check whether the document is
// ready. This is hacky, as the code below has to make assumption
// about the browser's inner working -- specifically that the `gBrowser`
// property should NOT be accessed before the document of the window is
// in its ready state.
