I recently changed or reverted a lot of the settings on my browser, including the theme. After having changed my preferences back to what they were, the pages opened when browsing files locally were stuck on the light theme. I tried disabling and reenabling the styles ect, and eventually went into the Web Developer Tools and found that the color-scheme in the dirListing.css was set to 'light dark'. Fixing the issue was as simple as changing the field to just 'dark', but obviously the issue returned as soon as I navigated to another page. As I couldn't find a way to alter the dirListing.css file itself, I was wondering if there's a way to reset it without uninstalling and reinstalling Firefox. Simply saving an altered version to import back in won't be helpful, as I would still need to import it to each new page I open. Thank you for helping.
