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, obtain sensitive
information, bypass same origin restrictions, conduct cross-site scripting
(XSS) attacks, conduct cross-site request forgery (CSRF) attacks, spoof
origin attributes, spoof the addressbar contents, bypass safebrowsing
protections, or execute arbitrary code. (CVE-2019-11709, CVE-2019-11710,

It was discovered that Firefox treats all files in a directory as same
