Allow Access to file URLs in Autofilling and Desktop Browser Extensions Posted September 3, 2018 · Edited September 3, 2018 by elm · Report reply In the Enpass Chrome Extension for Windows 7, there is an option / toggle called, "Allow access to file URLs", which for me, and by default, is set to OFF. I can't find any information on this option in the manual, or searching the forums. What is this option for? What does it do? See attached screen shot below.
