Title: Firefox vulnerabilities
Summary: Firefox could be made to crash or run programs as your login if it
opened a malicious website.

potentially exploit these to cause a denial of service, obtain sensitive
information, conduct clickjacking attacks, or execute arbitrary code.
Instructions: After a standard system update you need to restart Firefox to make
all the necessary changes.
