Dark theme issues

I was trying to change the interface from Hugo Light to Hugo Dark. It took five attempts at changing and clicking “save changes” for it to work. Is this a bug?

I do not have any problems on Chrome when changing the theme here:

But I cannot use the menu buttons to change themes; they throw JS errors.

I chose the interface option on the sidebar and then I tried to change it from there. But clicking save changes would do nothing. I repeated it five times and it reloaded and applied the change which I thought was strange.

I can confirm that it’s broken. That is probably due to Firefox restrictions. I can see some scripting errors in the console. You can always go to your profile and set your preferred colour scheme there. That one works.

I use a dark theme extension and I thought there was a conflict.
