It's a total crapshoot as to whether a theme will change the underlying UI to dark mode or light mode. There is no option to manually choose. It has a mind all its own. I use light mode everywhere but this add-on insists on forcing dark mode on the context menus and settings pages no matter what colors are chosen. But sometimes I get lucky and some random color combination results in light mode how I want it. This complete lack of control is fundamentally bad design.

It works fine I like it. It helps to identify which profile is in use currently. 4 star because one of my preset define as a dark theme and many page understand this as a system theme is dark. It could be a great extra to set the dark and the day colors as well.

Good Tool. Would have rated it higher but,
1. Exported themes won't install, they have to be signed by mozilla (a long winded process) and
2. The page layout for the popup menu box example, hides the saved themes option, making it impossible to select/change themes without zooming the page right down.

That said, exported and signed theme did install and work well. not really for novices.

If devs can fix these issues, its a excellent tool.

Pas de version en français, du coup je suis perdu dans tous les réglages.
Par exemple les textes dans les marques pages sont devenus très clair (beaucoup trop), et je n'arrive pas à trouver comment le régler car tout est en anglais !
Encore une perte de temps...

Created XPI file cannot be installed, browser says it is broken. :-( Tried several times and always the same result. :-(

very cool!

A recent update caused my custom there to start forcing dark/night mode on websites. This doesn't happen on some default themes, but on my custom one I can't find an option to return to a light theme. I liked it a lot before this update.

Would be 5*, but using a dark theme forces night mode CSS on websites that rely on the system theme. This is very undesirable, and should not be something controlled by the browser theme. Reading night-mode websites during the day is uncomfortable, meaning you have to disable this extension or launch the colors editor again to switch to a different theme.

Hey, thank you. Thank you and your dear colleagues for this very, very wonderful program you have made available to the general public. Thanks a lot

setting the toolbar color also changes the default background color for web pages; that should be a completely separate option

I don't know what I was expecting. I guess I thought it was going to allow me to not only set a bg image but also be able to see what the image actually is and maybe the entire navigation bar. Images only affect the tabs (windows 10). Uninstalled within 10 minutes.

... This plugin sets the dark mode on websites ...

Found a first solution with the additional installed addon 'automaticDark - Time-Based Theme Changer' of simonkhzhang. In settings of this addon set only 'Change themes based on the system theme' and both! 'Daytime theme: and Nighttime theme:' to light not to dark (german means hell anstelle dunkel). Hope this works for you. Kind regards, Gerald
