GREAT ! Easy-to-use and love some of the presets. Would be even awesome if, at startup, we do not notice the switch between the default browser theme and the new one with the plugin's version (in my case, switch from browser's integrated orange theme to a dark preset from this plugin).

Really fun and easy to use add-on :)

Endless fun customizing the colors of the various user interface elements.

It's great and easy to use. Although I'd like to have an updated version of the preview for Firefox proton

Incroyable add-on, très facile à prendre en main.

Pink and poisonous green as text/background combinationf for e.g. the application menu [I don't remember which was which and I am NOT about to try to reproduce the situation!] for make an eye-hurting, unreadable combination. The tools and options for color choosing were infinitely superior on the much less technologically sophisticated environment of Sun workstations 30+ years ago....

The browser starts with the default theme, and it takes a while to reload the correct theme created by color.firefox.com

It would be nice to have an option to automatically change themes based on the time of day, but otherwise this is as comprehensive a Theme Customizer as I could hope for.

I just wanted to tweak a couple of things but there is no setting provided for them so I can't.

I also don't care for some asinine quote about colour, I don't want a lifestyle magazine. I want a tool that let's me theme firefox without farting about with userChrome.css

what you should do is provide a decent box model and the associated CSS.

about:theme

and just have a page like the about:config

there. could code that in a day. maybe the management could take a pay cut to pay for some devs.

So back to farting about userChrome.css because Mozilla can't get it together to make a built-in theme editor.
