Mozilla.org has released security updates for its three main products: Firefox 0.9.3, Thunderbird 0.7.3 and Mozilla 1.7.2.
According to MozillaZine, four potential security holes were patched in this update. Because this was a security-related update, the Mozilla release notes are very short, offering only a link to the relevant Buzailla entries.
All three applications are available for Mac OS X, Linux and Windows. Download links are available at the Mozilla.org home page.
