An open source userscript manager that supports a lot of browsers
Priiv helps users to quickly choose and use the most privacy and security friendly settings across all of their accounts and apps. Users select the accounts they want to protect and can then choose among available recommended settings changes, and initiate these changes across multiple accounts with a single click. Priiv gains no access to user account credentials or tokens. The settings changes Priiv can execute are strictly limited to those that are Priiv-authorized and authenticated.
