NOTE: This bug only affects Firefox for Android. Address bar search suggestions in private browsing mode were re-using session data from normal mode.Firefox for Android would become unstable and hard-to-recover when a website opened too many popups.When styling and rendering an oversized "select" element, Firefox did not apply correct clipping which allowed an attacker to paint over the user interface.

The caching and suggestion techniques combined may have led to the title of a website visited during private browsing mode being stored on disk. When generating a filename for printing, Firefox usually suggests the web page title. Firefox used to cache the last filename used for printing a file.This was only possible if the website kept recording with the microphone until re-enabling the camera. When a user has already allowed a website to access microphone and camera, disabling camera sharing would not fully prevent the website from re-enabling it without an additional prompt.
