Q204: How can I allow Tampermonkey access to local file URIs?

A204 File access for Tampermonkey is only available at Chrome and derivates. In order to enable it open Google Chrome and click on the "More" icon (the three dots) in the top-right corner of the window. From the menu, select "More tools" and then click on "Extensions".

This will open the browser extensions page (chrome://settings/ or edge://extensions), which shows a list of all the extensions that are installed in your browser. Find Tampermonkey and click on the "Details" link to the right of its name.

On the extension's details page, scroll down to the "Permissions" section. Here, you will see a list of all the permissions that the extension has been granted. To enable file access, you will need to check the box next to the "Allow access to file URLs" permission. ( video tutorial)

Please note that local file access might need "Site access" set to "All sites" in order to work properly.
