Great extension. Simple to use. I'd love it if I could set two "default" themes (e.g. a light theme and a dark theme) and then hit a keyboard shortcut to toggle between the two!

i just wanted this, thank you

Working in FF 63.0.3 (64-bit).
Let you pick your installed themes from a drop-down list.
Simple, clear and useful.
Thumbnails / preview when hovering over a list item would be nice :-).
Thank You Tusharkanth

This does all I ask of it. ;)

Still working Firefox 62.0.2

Great addon, needs a better icon, can't see it on dark/black theme.

A simple and straightforward but useful extension that makes it even easier to switch between themes.

Doesn't recognize any of the themes I have installed. I'm on FF52 ESR.
