Firemonger Project

What a great Idea, putting an ISO together with both Firefox and Thunderbird, along with all the plugins, themes and extensions you need. Latest build was the 8th of May, there's even artwork for cd sleeves. Remember it's free. Click on my permanent Firefox link to learn more.
On another Firefox note, there is a security flaw at the moment, suggestion is to disable Javascript in Tools > Options > Web Features, until this has been resolved. More info again at The Firefox website.
