We are not lawyer, and so cannot give you formal legal advice. However I 
   can give you my opinion.

If you copied code from an existing file that is under the MPL/GPL/LGPL 
trilicense, then your source code file (or files) that contain that code 
must be under the trilicense as well. In other words, your source code 
files that contain the copied code should also contain a copy of the 
original license notices from the files where the code originated.

Could you clarify this? Do you mean that your extension requires 
Chrominframe to be already installed on the user's system?

This depends on whether you copied source code from ChrominFrame, or are 
simply depending on it to be installed separately. Please see my 
question above.
