Hello, tech enthusiasts! Today, we’re diving into an essential update from Mozilla regarding their Firefox browser.

Recently, Mozilla identified a security bug within Firefox for Windows that was actively being exploited in the wild. This issue prompted them to roll out an urgent update.

The fix is included in the latest version, Firefox 136.0.4, which addresses the bug noted as CVE-2025-2857. Interestingly, this flaw shares a similar pattern with a recently patched bug in Google Chrome.

Exploiting this vulnerability could allow attackers to escape Firefox’s sandbox, a security feature designed to limit access to a user’s system and data.

This bug isn’t exclusive to Firefox; it also impacts the Tor Browser, which has received an update in response. Security expert Boris Larin highlighted the interconnection between the Chrome and Firefox vulnerabilities.

For those who use Firefox or similar browsers, it’s crucial to update promptly to maintain your security against potential threats.
