Perfect !

Works perfectly! Love how it switches themes automatically by time.

On pc Mozilla browser it instantly started to work! Not yet sure about how I like all the colors and that, but I give 5 for that it instantly starts to work.

no bugs,working perfect with zen browser

I use a custom Firefox theme which is great - but it doesn't work well with Windows system dark mode. With this extension, you can define a Firefox theme to be used when Windows system dark mode is enabled / disabled.

Very good. I only miss a direct way to change the extension settings, for instance, clicking on its extension's icon.

"Change themes based on the system theme" doesn't work on windows with 'Auto Dark Mode' program but works just fine with my Macbook's native auto dark mode ^^
