thoughts on Klar served by the Guardian project after "recent" changes to Mozilla's approach to privacy

“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.

i was using Focus as a quick less secure browser that doesn't break official websites. I uninstalled it after Mozilla's changes to terms of use/service.

Is Klar, like IronFox, a cleaned fork? If not, why is Guardian project serving it as next level privacy?
