According to the release notes Firefox version 95.0.1 brings some as well as bug fixes, but no security fixes. Here's a rough overview of the bug fixes in the new Firefox, which the developers describe as: 

  • MOZILLA_PKIX_ERROR_OCSP_RESPONSE_FOR_CERT_MISSING error messages when trying to connect to various domains (bug 1745600), I covered this bug in the blog post Firefox cannot access … (Dec 12, 2021)
  • Fix for a WebRender crash on some Linux/X11 systems (bug 1741956).
  • Fix for a frequent crash when shutting down Windows (bug 1738984)
  • Fix web page contrast problems for some Linux users who have dark mode set at the operating system level (bug 1740518)

For Windows users, the MOZILLA_PKIX_ERROR_OCSP_RESPONSE_FOR_CERT_MISSING bug and Windows shutdown crashes are certainly relevant.
