“Private browsing” on most browsers isn’t comprehensive or easy to use. Klar is next-level privacy that’s free, always on and always on your side — because it’s backed by Mozilla, the non-profit that fights for your rights on the Web.

MADE BY MOZILLA
• We believe everyone should have control over their lives online. That’s what we’ve been fighting for since 1998.
