Mozilla and the Tor Project are in the early stages of exploring the inclusion of Tor's private browsing features within the Firefox web browser in the form of a privileged extension. This comes on the heels of a previously expressed intention of including some Tor capabilities within Firefox in the form of a Super Private Browsing mode according to Mozilla's public Research Grants 2019H1 report from May.
Mozilla is not the first to consider using Tor to boost the Firefox users' privacy, with Brave already having included the open-source online anonymity Tor software within its private browsing mode. Brave's newly acquired Tor capabilities allow its users to prevent tracking while browsing the web and protecting their privacy without having to install any additional software on their computers.
Bottom line though is that the normal "incognito" modes that Firefox, Chrome, etc have been offering have hardly been that at all, and it should also be remembered that another area of weakness often is the various 3rd party extensions that a user installs.
