- 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.
