Firefox Community Forum

Firefox claims does NOT save site/URL visit information while in Private Mode. And I thought that was true. However, I just discovered that Firefox DOES SAVE Private Mode URL/Site visits - in this specific place. I don't know how long the history will be saved - it looks like at least as long as the Window is open. I want to keep most of my open Private Tabs open - but want to Delete/Clear the ones I'm done with. I thought/understood that Private window/tab/visit info was not tracked/saved - and it's not saved in History, or Searchable. But it appears that this doesn't apply to the Recently Closed Tabs MenuItem. And there seems to be NO 'delete' or 'clear' option for this field. I can't find any reference to the subject in the Forum or Articles. The picture I've attached is NOT of the Recently Closed Tabs while in Private Browsing, but is the same MenuItem and field contents. Thanks for your interest. I'm hoping someone can help me figure out how to delete/clear this specific history.

I've noticed that occasionally, a site will show up twice in the history dropdown. It's not always a thing that happens, but it does happen. Clearing history obviously wipes this out, but I'm not sure why it's happening in the first place.

I'm not talking multiple pages sharing a listing or anything. It's literally instances where certain sites will just show up twice in the history. I've noticed it seems to happen a lot when I open a video in Youtube in a spare tab rather than just clicking on a video on the main page.

I'm on version 142.0.1 of Firefox, and just updated to it two days or so ago. I'm on Windows 10 version 1909. Anyone know what's causing this?

Edit: I'm including an image of the glitch. This happened just after I clicked on a video. I did not hit reload or anything, and the video simply appears in the history twice. It occasionally happens with other sites, too.
