Browse like no one’s watching. The new Firefox Klar automatically blocks a wide range of online trackers — from the moment you launch it to the second you leave it. Easily erase your history, passwords and cookies, so you won’t get followed by things like unwanted ads.

“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.
