The Mozilla Foundation reports:

Redirection from an HTTP connection to a data: URL assigns the referring site's origin to the data: URL in some circumstances. This can result in same-origin violations against a domain if it loads resources from malicious sites. Cross-origin setting of cookies has been demonstrated without the ability to read them.

< 50.0.1,1

Mozilla Foundation reports:

Jann Horn 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.

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 performance.now() has been reduced from 5μs to 20μs, and the SharedArrayBuffer feature has been disabled because it can be used to construct a high-resolution timer.
