I know that the dark mode setting is disabled by Resist Fingerprinting. I am not using that, I am using the Dark Reader extension. The extension still doesn’t work, but it works on Firefox.
Other extensions I have installed: Ublock Origin, Decentraleyes, Skip Redirect, Onetab, Old Reddit Redirect
Librewolf version: 124.0.1-1
It works for me without any Problems. Are you using the flatpack?
Yes, I am using the flatpak version. I’m on Debian and there is only the flatpak version.
Firefox is also flatpak.
