Mozilla Patches Critical Firefox Bug

Mozilla has released updates to fix a critical security vulnerability affecting its Firefox browser for Windows, just days after Google patched a similar flaw in Chrome that was actively exploited as a zero-day vulnerability. The security vulnerability, CVE-2025-2857, has been described as a case of improper handling that could lead to a sandbox escape. This flaw is similar to the one recently patched in Chrome, which allowed a sandbox escape.
