Debian and Mozilla are having copyright conflicts?

It looks like Mozilla and Debian are having issues with copyrights, which is odd because last time I checked they are both open software companies, meaning that their software and source if offered for free everywhere on the Internet. It seems that since Debian (and Ubuntu) are distributing their operating systems with Firefox named Firefox but not with the Firefox logo that Mozilla (the parent company) wants them to either put Firefox in the operating system with the Firefox logo or to change the name for Debian releases.

On the other side of the tracks Debian doesn't believe that Firefox is truly free because the logo (think icon) is trademarked by Mozilla so it isn't completely free to use. The conflict looks heating and the emails are getting nasty, who knows what exactly will come out of this recent news. Hopefully they will call a truce and just use the Firefox logo in Ubuntu. I know the blue logo they use now is much less sexy then the regular Firefox logo.
