PSA: Homeland Security says to update Firefox now
Like, right now.

If you use Mozilla’s Firefox, go update your shit
Mozilla has just fixed a zero-day in both Firefox and Firefox ESR that seems serious, as even the Department of Homeland Security has issued an advisory note about it. While we don’t know exactly what malicious actions someone exploiting it could do, patching security holes on your computer is always the right thing to do. The bug only affects Firefox and Firefox ESR users on macOS, so if that’s you, go update.
- The advisory on the security exploit came from the Department of Homeland Security’s cyber protection division, CISA
- Mozilla says it isn’t just a theoretical risk – they have seen it in action “We are aware of targeted attacks in the wild abusing this flaw.”
- Other recent zero-day exploits in Firefox were targeting cryptocurrency holders
Firefox for iOS is unaffected, as it’s really a reskinned version of Safari. Windows users of Firefox are unaffected (as far as we know), but it never hurts to check for updates regularly and keep your software current.
