OK, so perhaps the whole scandal with Mozilla was nothing to be concerned about whatsoever. We need to just calm down some.

What’s the purpose of this document?
This document sets out to answer the common questions which arise about the use of the Mozilla Trademarks and Logos. Our code is free, but we do strictly enforce our trademark rights, we must, in order to keep them valid. This means that, while you have considerable freedom to redistribute and modify our software, there are tight restrictions on your ability to use the Mozilla name and logos, even when built into binaries that we provide.
What are the Mozilla Trademarks and Logos?
The Mozilla trademarks include, among others, the names Mozilla®, mozilla.org®, Firefox®, Thunderbird™, Bugzilla™, Camino®, Sunbird™ and Seamonkey™, as well as the Mozilla logo, Firefox logo, Thunderbird logo and the red lizard logo.
The default logos in CVS which are built into Firefox and Thunderbird by default (i.e. the globe without the fox, and the original blue bird) are explicitly not protected as Mozilla trademarks. The files themselves are available under the mozilla.org tri-license; you can do anything you like with them under those terms…. Source: Mozilla
