  - Operations on a BigInt could have caused uninitialized memory to be exposed.

  - Heap buffer overflow in WebGL.

  - Use-After-Free in WebGL.

  - CSS Sanitizer performed incorrect sanitization.

  - Incorrect cast of StyleGenericFlexBasis resulted in a heap use-after-free.

  - Malicious applications on Android could have induced Firefox for Android into sending arbitrary attacker-specified headers.

  - HTTPS pages could have been intercepted by a registered service worker when they should not have been.

  - URL spoofing via unresponsive port in Firefox for Android.

  - Internal network hosts could have been probed by a malicious webpage.

  - When entering an address in the address or search bars, a website could have redirected the user before they were navigated to the intended url.

  - The proxy.onRequest API did not catch view-source URLs.

  - Opening an extension-less download may have inadvertently launched an executable instead.

  - Memory safety bugs fixed in Firefox 84 and Firefox ESR 78.6.

  - Memory safety bugs fixed in Firefox 84.");
