• Body search/filtering didn't reliably ignore content of tags
• Inappropriate warning 'Thunderbird prevented the site (addons.thunderbird.net) from asking you to install software on your computer' when installing add-ons

Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, gain additional privileges by escaping the sandbox, or execute arbitrary code.
