If you are using Mozilla Organization's Firefox Web browser then you might need to install an update to protect your systems against possible attacks. On September 29 Alex Vincent reported a vulnerability that might allow intruders to delete files on a user's system. Mozilla issued an update for the Browser on October 1st.
To determine if you have a vulnerable version of the browser select Help, and About Mozilla Firefox from the pulldown menus. At the bottom of the dialog you should see text that includes " Firefox/0.10.1." If you don't see that text then you probably have a vulnerable version and should load the update as soon as possible.
To load the patch you can read the bulletin at Mozilla Organization's Web site where you'll find a link to the update along with other technical details. Or you can use Firefox's built-in update tool by selecting Tools, Options, Advanced, and then scroll down to the Software Update section and click the button labeled "Check Now," which will download the update.
