Hi, do you mean the one assigned CVE-2023-4863? Mozilla issued Firefox 117.0.2 and 115.2.1 to address the problem. See: https://www.mozilla.org/security/advisories/mfsa2023-40/

The reason for mentioning that patch is: this extension uses features Firefox makes available to add-ons and web page scripts; the extension does not have its own image conversion libraries.
