It works, that's everything to say about. Good replacement to the Persona changers I used back when this was a thing.
Would be great to have the ability to choose, which themes to be skipped. In my case it ultimatively skips the colored Firefox themes I downloaded to use along with the default dark, light, automatic and alpenglow ones I would agree on skipping as those can't be uninstalled.

What a beautiful extension.
I would also love the option to create sets of themes which are used, e.g. only dark themes. But other than that, it does what it said, respect.

This is exactly what I was looking for!

I needed this, great job :)

With Thematic this one is totally useless and dim-witted. Thematic allows me to change the themes at specified intervals like every 2 minutes. Why would I just change it once only at startup?

Great indeed. I suggest you to make an option to change theme only after several browser starts or after several days?

I love it! It makes it so much easier to change a theme without all the hassle!

Hello! Can you add icon to toolbar to change theme with 1 mouse click? Is it even possible?
Or you can add extensions shortcut! YES!
That would be great!)

Great! It's what I want.

Just a small issue: the "Change now!" button doesn't work in Private Mode.

But still good work! I love it.

Works perfectly fine. only thing is that you gotta wait like 2 seconds for the switch to happen after you start the browser, but thats not worth -1 star. good job!

Simple, effective, works perfectly, great all around

A rotator that works, yay. This would be six stars if I could have it rotate on a timer while the browser is open. Please consider this functionality.

The only theme rotator I can find that actually works in current Firefox versions. My main request would be that the rotation could be on a timer instead of having to be at startup. (I can leave the browser up for days at a time.)

I love random mode at startup nice option.Thank you!
