    Details: USN-3761-1 fixed vulnerabilities in Firefox. The update caused several regressions affecting spellchecker dictionaries and search engines. This update fixes the problems. We apologize for the inconvenience. Original advisory details: Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, or execute arbitrary code. (CVE-2018-12375, CVE-2018-12376, CVE-2018-12377, CVE-2018-12378) It was discovered that if a user saved passwords before Firefox 58 and then later set a master password, an unencrypted copy of these passwords would still be accessible. A local user could exploit this to obtain sensitive information. (CVE-2018-12383)
