Went back and forth between the following:
Vanadium - secure Chromium browser installed by default on GrapheneOS, Bromite/Cromite - alternative secure/private Chromium browser, Quetta Browser - private Chromium browser that comes with an AI-based ad blocker and extension support, IronFox - private Gecko browser that is as hardened as LibreWolf or Mull Browser.
Right now, I’m daily driving Cromite and IronFox, the former now having extension support via Developer Options, which allowed me to enable and install extensions like uBlock Origin Lite and “I Still Don’t Care About Cookies”.
Hard agree that bookmark import/export would make transitioning to IronFox much more incentivizing, but aside from that, I love how hardened it is.
