several minor regressions. This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
Multiple security issues were discovered in Firefox. If a user were
tricked into opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service, obtain sensitive
information across domains, or execute arbitrary code. (CVE-2023-5722,
CVE-2023-5724, CVE-2023-5728, CVE-2023-5729, CVE-2023-5730, CVE-2023-5731)

browser prompts and dialogs due to an insufficient activation-delay. An
attacker could potentially exploit this issue to perform clickjacking.

containing invalid characters. An attacker could potentially exploit this
issue to cause a denial of service. (CVE-2023-5723)
