Port Persistent Mode to Tor Browser
💡 Proposal
User Story
Some users want to opt-in to remembering login information and other site data between browsing sessions. Tor Browser currently uses Always on Private Browsing mode by default, meaning all history and cookies etc get wiped on browser restart. Porting Mullvad Browser's persistent mode will allow users to optionally remember such data between sessions.
Security and Privacy Implications
This mode would require users to opt-in and some sort of on-boarding process to ensure users understand the subtleties between the two modes of operation. Browsing data will be written to disk and deleted on browser exit, rather than not being written at all (technically this is an oversimplification, even in Private Browsing mode some data is written to disk in an encrypted fashion). This feature may require some tweaking rather than a direct port to ensure we adhere to the Tor Browser design document
Security
Users will be able to opt-in to persisting state to disk (e.g. cookies) on a per first-party basis. Additionally, browsing state may be written to disk and subsequently cleaned up on browser exit/start which alters the risk for those users whose adversaries can have physical access to their machines (e.g. your employer's IT department, members of your household, etc).
Privacy
This feature does not affect privacy.
Accessibility Implications
This feature does not affect accessibility.
