I thought that in Private browsing mode, using Tools > Settings > Privacy & Security > Clear Data > Clear > Clear Now cleaned out everything in mid-session. It turns out that's not true, for example, using Firefox View I found that the list of Recently closed tabs in three-bar menu > History > Recently closed tabs was NOT cleared. The only way to see that was with Firefox View, which you could then use to delete items from the list.
With the new version of Firefox (119.0) Firefox View has been removed from Private browsing mode entirely. Thus not only is it impossible to see if the recently closed tabs list has been cleared, but it's impossible to clear the list even if you could see it. That leaves the only way to be (fairly) sure things are cleared out during a Private browsing session is to close the browser entirely, which is an annoying pain.
Why was that feature removed? How can I tell if the recently closed tabs have been cleared without it?
