+ <p><strong>Jann Horn</strong> of Google Project Zero
+ Security reported that speculative execution performed
+ by modern CPUs could leak information through a timing
+ side-channel attack. Microsoft Vulnerability Research
+ extended this attack to browser JavaScript engines and
+ demonstrated that code on a malicious web page could
+ read data from other web sites (violating the
+ same-origin policy) or private data from the browser
+ itself.</p>
+ <p>Since this new class of attacks involves measuring
+ precise time intervals, as a parti al, short-term,
+ mitigation we are disabling or reducing the precision of
+ several time sources in Firefox. The precision of
+ <code>performance.now()</code> has been reduced from 5μs
+ to 20μs, and the <code>SharedArrayBuffer</code> feature
+ has been disabled because it can be used to construct a
+ high-resolution timer.</p>
