A use-after-free was discovered when manipulating HTML media content in
some circumstances. If a user were tricked in to opening a specially
crafted website, an attacker could potentially exploit this to cause a

the privileges of the user invoking Firefox. (CVE-2015-4509)

Looben Yang discovered a use-after-free when using a shared worker with
