Almost perfect theme maker, a few things I would improve is having a actual pop-up show up to see what it looks like when choosing color, also I'm having the same issue as many have with not being able to make the homepage dark as well like normal default dark mode, would appreciate a toggle setting.

I was repeatedly sent to Firefox Color to this to "create my own theme" after update to 68.2esr removed my UI. Have created and saved 5 times but the theme is gone on restart. There are no instructions on how to "add" the saved theme to my themes. Is this just a toy? Or can I somehow continue to use the theme I want? Is there any info on this anywhere? Nice interface and easy to use, but a disappointing waste of time so far.

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.

It's an incredible tool.

Dark themes can't be set. I have the background color for the tabs, etc. set to a dark color. As soon as I minimize FF70, it all changes to white. The same with themes made by others.

I loved it so much before but now not so much because the tab background color is white no matter what theme I choose. Can the developers please fix this?

Edit [2/27/2020]: I uninstalled then re-installed the extension and everything works fine so far!

This is a fantastic extension however, there is one caveat: The new tab page supports dark mode, this extension does not leaving it always white, I really think it'd increase the functionality of this extension greatly just adding a dark/light mode toggle checkbox to the themer, been wanting this since it was in beta please add it!

It should be far more better if come with macOS dark mode support!!!!

I had it and loved it but I had to re-install Firefox.
So i re-installed Firefox Color 6 or 7 times and it still does not work. IF IT EVER WORK I WILL RATE IT AT 6/5 BUT FOR NOW I CAN'T RATE IT AT 0

Real time theme editing, with a beautiful and intuitive interface. This extension is amazing.

Great extension which offers a similar level of browser interface customisation as Vivaldi. However, I do wish certain elements colour could be changed independantly or all together, such as the toolbar icons & text, search sugestions hover colour, Bookmark Page icon, Screenshot icon etc...This extension currently also disables the dark background on the Firefox Homepage & Notes title bar, with no apparent method of changing it back.

It's good to customize firefox but i want a function that let you make the homepage background black

cool. so you get to make your own backgrounds and more!!! please install!!!

I really like this add on, and very much enjoy creating my own themes with it. But i would like to create and save more than just three. Maybe you could make that possible, dear developers?
