Bugzilla

At https://searchfox.org/mozilla-central/rev/f118dae98073bc17efb8604a32abfcb7b4e05880/browser/base/content/browser.js#3566 can we sub out

```js
  for (let tab of gBrowser.selectedTabs) {
```

with

```js
  let tabs = gBrowser.selectedTabs;
  if (!tabs.length) {
    tabs = [gBrowser.selectedTab];
  }
```

with a code comment explaining why this is necessary? I think that should fix the issue you describe.
