Firefox 3.0.19 is the end of the line for the browser version that debuted in 2008. Also released to fix security problems: Firefox 3.5.9 and Thunderbird 3.0.4.
After a lot of futile trial and error, the only way to get version 3.0.5 of Mozilla's Firefox browser on my PC was to uninstall version 3.0.4 first.
