The error page for sites with invalid TLS certificates was missing the activation-delay Firefox uses to protect prompts and permission dialogs from attacks that exploit human response time delays. If a malicious page elicited user clicks in precise locations immediately before navigating to a site with a certificate error and made the renderer extremely busy at the same time, it could create a gap between when the error page was loaded and when the display actually refreshed. With the right timing the elicited clicks could land in that gap and activate the button that overrides the certificate error for that site.

When typing in a password under certain conditions, a race may have occured where the InputContext was not being correctly set for the input field, resulting in the typed passwod being saved to the keyboard dictionary.

Mozilla Firefox before 28.0.1 on Android processes a file: URL by copying a local file onto the SD card, which allows attackers to obtain sensitive information from the Firefox profile directory via a crafted application.

The session-restore feature in Mozilla Firefox before 28.0 and SeaMonkey before 2.25 does not consider the Content Security Policy of a data: URL, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted document that is accessed after a browser restart.
