Firefox Branding

From Freespire

Why doesn't Freespire call their browser Firefox and their email program Thunderbird? Aren't they the same thing?

The default browser and email client in Freespire are based on Firefox and Thunderbird, but we make dozens of modifications to these programs. For this reason, trademark law and Mozilla trademark policy prohibit us from calling these programs Firefox and Thunderbird.

  From Mozilla’s Trademark Policy:
  
  Serious Modifications
  
  Those taking full advantage of the open-source nature of Mozilla’s products
  and making significant functional changes may not redistribute the fruits of
  their labor under any Mozilla trademark. For example, it would be inappropriate
  for them to say “based on Mozilla Firefox”. Instead, in the interest of
  complete accuracy, they should describe their executables as
  “based on Mozilla technology”, or “incorporating Mozilla source code.”
  They should also change the name of the executable so as to reduce the chance
  that a user of the modified software will be misled into believing it to be a
  native Mozilla product.

For this reason, we rename these products to Web Browser and Email. (The binary file names are Lbrowser and Lmail.)

Because we make so many changes to these programs, it's understandable that the Mozilla organization wouldn't want us calling them Thunderbird and Firefox, because that would be confusing, because no one would know which was which. "Would the REAL Firefox please stand up?"

If desired, Freespire/Linspire users can use apt-get or CNR to install "the real" Firefox from CNR.com.
