Overview
- Mozilla published Firefox 152 for Windows, macOS, Linux and Android and closed more than 40 security flaws listed in MFSA2026-57, including 11 high-risk issues and four that could allow escapes from the browser sandbox.
- The Settings interface was rebuilt to improve discoverability, removing the old “General” page and moving options into task-focused sections such as Appearance, Accessibility, Languages, and Tabs and Browsing.
- Privacy and playback controls were expanded with a per-tab tracking-protection exception in Private Browsing, a tracking-summary widget, context-menu video controls for play/pause/loop/fullscreen, and an address-bar quick action to mute all tabs.
- On mobile, Firefox 152 brings Tab Groups to Android with iOS support promised later, and the integrated free VPN remains a region-limited beta that has a temporary summer expansion of server locations for eligible users.
- Mozilla published a public roadmap and shipped matching ESR security updates while committing to weekly fixes as it prepares additional experimental features in Firefox Labs such as JPEG XL support and later integrations like PDF tools, containers and mobile VPN.
