libmozjs-dev package can't install

[Rashkae]

I was trying to install build dep packages for gxine (since the one 
included with Karmic is in really bad shape.) and stumbled on this 
package.  libmozjs-dev requires un-install firefox (and 18 other firefox 
related packages,) which makes no sense to me.  I will file a bug 
report, but first wanted to ask the question here in case there is, in 
fact, a reason for this package to be like this.
