Running win 10 I have a document on my desktop that I would like to open with firefox. I have that figured out using a batch file. I am opening firefox with the -new-instance -private along with the -url with path to the document. I want to open firefox in this specific instance using the "new window without toolbar" addon as it is ideal for this particular application. My question is how do I default to this option for this particular application, while keeping firefox with my bookmark toolbar and other options as my default browser in general usage.
