A wrong lowering instruction in the ARM64 Ion compiler resulted in a wrong optimization result.

When a secure cookie existed in the Firefox cookie jar an insecure cookie for the same domain could have been created, when it should have silently failed.

If multiple instances of resource exhaustion occurred at the incorrect time, the garbage collector could have caused memory corruption and a potentially exploitable crash.

An attacker could have caused memory corruption and a potentially exploitable use-after-free of a pointer in a global object's debugger vector.

Firefox did not properly handle downloads of files ending in <code>.desktop</code>, which can be interpreted to run attacker-controlled commands.

Using a redirect embedded into <code>sourceMappingUrls</code> could allow for navigation to external protocol links in sandboxed iframes without <code>allow-top-navigation-to-custom-protocols</code>.

A website could have obscured the fullscreen notification by using a combination of <code>window.open</code>, fullscreen requests, <code>window.name</code> assignments, and <code>setInterval</code> calls.
