I have some HTML-files on my local drive. They include some css files.
The devtools show a red error bar with this text
Allow links to local files is enabled.DE
Stildokument konnte nicht geladen werden. file:///C:/path-to/style.css
EN (translated by me)
Shylesheet could not be loaded. file:///C:/path-to/style.css
resource: and file:// is in whitelist.
There are no errors in devtools console.
Curiously the style rules take effect within that page but the files are not visible in style editor and a marked element in inspector shows no rule in the styles pane.
Firebug and devtools on Chrome 57.0.2987.110 are ok.
When I completely disable NoScript then all is fine with FF devtools.
How can this be fixed?
