Nicolas Chevobbe f1c59fa2b8 Bug 1688445 - [devtools] Fix browser/browser_window_close.js intermittent. r=jdescottes.
The test seemed to fail because the page was already loaded when we started
awaiting for `BrowserTestUtils.browserLoaded`.
This patch removes it and instead pass an `url` param to `BrowserTestUtils.waitForNewWindow`,
which means we'll wait for the page to be loaded.
