The customization is very good. The only unfortunate thing about it is that I can't find any way to apply it.

Je suis content de pouvoir choisir les couleurs de mon thème puisque la plupart des thèmes existants ne me plaisaient pas trop. Malheureusement, comme beaucoup l'ont déjà commenté, on ne peut pas choisir si le thème devrait être considéré comme sombre ou clair, en l'occurence je voulais un thème sombre. Il serait d'ailleurs encore mieux si l'on pouvait choisir les autres couleurs tout simplement (nouvel onglet, paramètres, ...). Je pense qu'il serait aussi appréciable de pouvoir changer la couleur de highlight de la barre de recherche quand on est dessus.

Eigentlich cool, nur das "Neue Tab" Fenster ist weiß, obwohl alles andere im Darkmode ist. Schade, ein kleiner Punkt, der alles zertört. Wenn das gefixt wird, 5/5 Sternen.

this extension is cool but it should not disable dark mode in new tab

Every time I create a theme and tried to apply it to my browser, it says that the xpi file is corrupted. I had to take it off. It really looks like a good apps to add to Firefox. Bummer!

Es una buena extensión, pero sin duda incompleta.
Si bien deja personalizar casi todos los aspectos de las pestañas, no tiene la posibilidad de modificar el fondo de ''nueva pestaña'' por lo que se queda en blanco. Si tienes todo oscuro o trabajas de noche acaba siendo bastante molesto y casi obligandote a no usar diseños personalizados para ponerlo en modo oscuro.

needs to improve because you only can change few things

The color picker and the examples aren't anywhere near accurate. I can still do what I want by watching the actual browser change colors, but the add-on should be fixed since it isn't right, and just like with everything else these days, if a person would test what they make before they call it done, there would be a lot more satisfied people.

No matter what theme I try to put on my Firefox Color Theme it keeps going back to blue polka dots.

Windows 8.1安装了FireFox Color，自定义之后，右上方的按钮还是系统的样式。虽然没什么大问题 但还是看着不太舒服...

Прикольно

Lately Firefox has not been restoring my colors when I restart, until I revisit color.firefox.com in a new tab.

After exporting, the add-in does not have the correct structure. The XPI file contains only two files: "manifest.json" and "0.png". The exported theme has an incorrect design and cannot be installed.

Fun and with lots of options, but you are then forced to use a light theme everywhere.

Cool way to customize the tabs/top bar colors, but disregards previously existing theme you may have. This makes sense, but it removed the dark theme from the about:newtab page. Plus, a new instance loads with the last theme in use before flashing over to your custom theme. In all, cool idea, but needs work.

I use the Firefox Dark Theme and I really like it, but i wanted change on thing. But this is not possible with this Add-on
