The maintainers of the Tails project have issued a warning that the Tor Browser that's bundled with the operating system is unsafe to use for accessing or entering sensitive information.

"We recommend that you stop using Tails until the release of 5.1 if you use Tor Browser for sensitive information," the project said in an advisory issued this week.

Tails, short for The Amnesic Incognito Live System, is a security-oriented Debian-based Linux distribution aimed at preserving privacy and anonymity by connecting to the internet through the Tor network.

The alert comes as Mozilla on May 20, 2022 rolled out fixes for two critical zero-day flaws in its Firefox browser, a modified version of which acts as the foundation of the Tor Browser.

After you visit a malicious website, an attacker controlling this website might access the password or other sensitive information that you send to other websites afterwards during the same Tails session," the Tails advisory reads.

The weaknesses don't break the anonymity and encryption protections baked into Tor Browser, meaning that Tails users who don't handle sensitive information can continue to use the web browser.
