Title: Firefox vulnerabilities
Summary: Firefox could be made to crash or run programs as your login if it

potentially exploit these to cause a denial of service, overlay text
over another domain, or execute arbitrary code.
Instructions: After a standard system update you need to restart Firefox to make
all the necessary changes.
