- SafariApple's browser is praised for privacy protections, battery efficiency and Apple device integration, though critics cite aggressive tab reloading, sites that only work in Chrome, and iOS engine lock-in.307recommend
- Orion Browser by KagiA WebKit browser recommended for running Chrome and Firefox extensions like uBlock Origin on iPhone and Mac, with no telemetry, but critics cite bugs and its closed source.206recommend

Recommends · Apr 2026 · in “Mozilla Thunderbolt”
The LibreWolf browser, and if need be the IronFox browser for Android, should have been installed and analyzed in parallel with Brave

The solution for the (as of yet) small group of people who cares about these things is very simple: community driven forks.

Firefox is only good for getting forked into better browser like Mullvad Browser, LibreWolf and Tor Browser.

Both are good but Librewolf comes with history and cache disabled by default which may be bit surprising.
