GoKawiilMozilla and Google ship major security updates for Firefox 159 and Chrome
Mozilla released Firefox 159 for Windows, MacOS, Linux and Android, fixing 167 security bugs, 108 of them rated high severity, many involving use-after-free memory flaws and sandbox escapes.

Firefox 159 also adds new features such as a MacOS share picker and sidebar access to saved passwords.
GoKawiil's interpretation of the reporting above, not reported fact.
The scale of these patches suggests attackers have multiple potential entry points into two of the world's most widely used browsers, making prompt updates important for everyday users. The presence of sandbox-related flaws in Firefox is notable because sandboxes are meant to contain malicious code, so bypassing them could let attackers execute code outside the browser's protections.
- Firefox 159 fixes 167 bugs, 108 rated high severity, including many use-after-free flaws.
- Chrome's latest update resolves 52 vulnerabilities, four classified as critical.
- Users should manually update both browsers immediately rather than wait for automatic updates.
