“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.

• Easily erases your history — no passwords, no cookies, no trackers
BROWSE FASTER
• By removing trackers and ads, Web pages may require less data and load faster
MADE BY MOZILLA
• We believe everyone should have control over their lives online. That’s what we’ve been fighting for since 1998.
