When opening a new Private Tab, there is a notice that reads:
"Leave no traces on this device. Firefox deletes your cookies, history, and site data when you close all your private windows. Who might be able to see my activity?"
I believe "no traces" is misleading. Unless explicitly overridden (not just deleted), some data from browsing sessions could be extracted using digital forensics tools from a disk image. Especially in a time when people are looking for more confidence in their devices' security, a statement like this is confusing.
