A covered pick. Anyone can use it as a private drop-in, with no setup or know-how. Enough for most people. Threat levels
Our take
A stripped-down mobile browser that blocks trackers by default and forgets everything when you tap erase, which is its entire appeal. That same simplicity is the limit: no real tab management, no extensions, and not meant to be your only browser. Keep it on your phone as the quick, disposable browser for one-off links and searches; use a full browser for anything you actually want to keep.
