Firefox Android 152.0.6 - Private Browsing not deleting browsing history?

I might have stumbled upon a pretty concerning bug on Firefox Android where closing all private tabs (either from the notification bar, or closing every private browsing tab in the app, seems to not delete my browsing history from the private session.

Steps to reproduce:

  • In Private Browsing, log in to Reddit (or make a search on Google Maps)

  • “close all tabs” from your notifications shade

  • Open private browsing again, go back to the website you opened. I’d still be logged in/my previous searches show up in the suggestions.

Using 152.0.6 on a Pixel 9 Pro if it helps! Anyone else has the same problem? FWIW I don’t have the same issue on Firefox Focus with the same device.
