The Developer Tools feature suffers from a XUL injection vulnerability due
to improper sanitization of the web page source code. In the worst case,
this could allow arbitrary code execution when opening a malicious page
with the style editor tool. This vulnerability affects Firefox ESR < 52.3
and Firefox < 55.
