How to use local files as wallpapers
Firefox currently does not allow WebExtensions to access 'file:///...' URLs. However, until that becomes possible, New Tab Tweaker does support the following workaround:

1. Install HTTP File Server (HFS)
2. Host your wallpaper directory on HFS.
3. Add the following line to the wallpaper URLs textbox in New Tab Tweaker's options (without quotes): '[list] http://localhost/[WP]/?tpl=list'. Where '[WP]' is the path to your wallpaper directory on HFS. If that directory contains sub-folders with images, replace '?tpl=list' with '?tpl=list&folders-filter=\&recursive' instead.

The URL above will instruct HFS to build a list of all files in your wallpaper directory. The [list] tag at the front of the line tells New Tab Tweaker to treat the URL not as an image, but as a list of URLs to images. One will be selected randomly from among them. You can configure HFS to launch at system start for your convenience.
