Suggestions: This addon shoul not change almost all colors of the dark theme after it was installed. It should be able to edit the current color values of the current theme. It should supports hex value.

I love this thing. I do have some suggestions though. First, it would be really nice to be able to sync my saved custom themes across my computers. Second, I tried saving my theme so I could copy it to my other computers, but the theme was rejected as corrupted by the other computers when I tried to use it. Third, it would be nice to be able to put names on the themes when you save them instead of only when exporting. Having names you can see when in the Color UI would be really helpful.

Would be great as I easily created my own custom theme (Spider-Gwen) but now my last created settings in Firefox Color are set as my theme every time Firefox fully initializes after closing overriding my current theme selection, which I then have to go into the settings to deactivate my theme, then reactivate it to overwrite what Firefox now thinks is my default theme from Firefox Color.

Хорошее расширение. Было бы неплохо добавить возможность менять цвет фона и текста в боковой панели.

Good addon. It would be nice to add the ability to change the color of the background and text in the sidebar.
