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.

Since the settings haven't given that option for years, the best way to have a local file as the new tab page was using autoconfig.cfg + autoconfig.js, as described in this thread: https://support.mozilla.org/en-US/questions/1251199 But since the most recent update (v136.0), this stopped working.

The New Tab Override add-on has its own issues with using local files (can only load a .html file, no local CSS/JS, can't give a blank address bar for me to search in), so it doesn't solve the issue either.

This is very important to me, and others have been asking for this feature back for years. It feels awful to have the working solution stop working, in the browser that's supposed to be open and customizable.
