Specifically, what doesn't Malwarebytes like about the prefs.js file?
Unfortunately, the "Important Modified Preferences" listing isn't a complete version of what's in the prefs.js file.
What was the full error message? It might include a line number that is the problem.

This is the data after, I let malwarebytes quanrantine the prefs.js file. These are the emtries after the printer stuff:

There was no more info thanks. I saw something on the malwarebytes forum that said that this file modifies the preferences.js and that the change could have been allowing mixed content or pup did not know what that might be refering to but seemed that if the prefs.js was deleted I would not be adversely affected as I had made no customizations to speak of.
