I've just published a Trisquel development release containing Firefox 5.0, and instead of rebranding it I made all the changes in files separated from the Firefox package, in an attempt to avoid making changes to it and falling into trademarks limitations. But I was wrong.
Not only my trick wouldn't work, as the trademark license[1] also prohibits the inclusion of external modifiers that would be loaded by the plugin system(!), but as I was pointed out, an unmodified Firefox package which follows the trademark license can't be charged for. So, what we have here is a program under a proper free software license (ignoring the fact that it recommends non-free stuff) that has actual distribution restrictions. I think trademark licenses that say "if you modify it, you have to rename it" are ok, but this one says "if you don't rename it, you can't distribute it for a fee". * Does it render the program non-free? * How does it affect the software license it ships under? * Do you know of any other trademark license that restricts distribution or usability? [1] https://www.mozilla.org/foundation/trademarks/policy.html -- Firefox(TM) is a f****** trademark of the Mozilla(R) foundation.
