I'm seeing this as well, but only in Firefox View, not any of the other history > recently closed tabs menus. It looks like we're not passing a window object in `getClosedTabsData` [here](https://searchfox.org/mozilla-central/source/browser/components/firefoxview/recently-closed-tabs.mjs#171). Changing that in recently-closed-tabs to use `getClosedTabsData(getWindow())` solves the issue but it seems like defaulting to not using closed tabs from private windows should be the default if no window object is passed in. I think this is an easy fix based on the work sfoster did in 1819675.
