Mozilla released emergency security updates to address two Firefox zero-day vulnerabilities demonstrated in the recent Pwn2Own Berlin 2025 hacking competition.

The fixes, which include the Firefox on Desktop and Android and two Extended Support Releases (ESR), came mere hours after the conclusion of Pwn2Own, on Saturday, where the second vulnerability was demonstrated.
