no funciona

it works but sometimes it glitches and erases all the themes i have made, idk if it's just me or if this add-on is doing it

Nothing speacial. I just find good theme for myself and add it "Fankots Theme by Fantron".

The colors are nice to costumize. Unfortunately UNUSABLE because after opening Firefox it takes an additional 2 Minutes loading the theme before you can start doing anything.
How on earth can you design an addon JUST for some colors consuming SO MUCH ressources??? I really have to control my anger here. Unbelievable.

NO ME DEJA USAR LO QUE YO CREO , QUIERO FONDO GRIS !!!!, PORQUE NO HAY UN FONDO GRIS???,,,O ES BLANCO O ES NEGRO UNA PORQUERIA..!!!! ESTOY PODRIDO!!!

setting the toolbar color also changes the default background color for web pages; that should be a completely separate option

I installed the extension because I wanted to add color to the top bar. I made some changes and exited the setup to see the results. But I couldn't find a way to get back to the setup. Finally, I uninstalled it and reinstalled it. But the same thing happened; I couldn't get back to the setup page. So I'm going to uninstall it and hope I can find a way to actually use the extension.

Firefox Colors represents the whole sad history of Firefox and Mozilla. Starting with the best of intentions, and then like a machine rolling through mud, accumulating sludge as it progresses till it is unrecognisable and impossible to use. Gets a good cleanup and starts all over again.
I agree with many of the others, who, like me, are frustrated at this stupid implementation. Every change appears to be irreversible. I have lost all my careful colour setups of versions past. Oh well, there are probably some idiots in a room somewhere patting themselves on the back and thinking they did a great job - so this won't change.
It's okay, we are almost at the point in the Firefox cycle where I drop off and walk with relief towards Chrome...

I hate it

doesn't load the page, i opened the extension, went off, played a game for an hour, came back and was confused by a blank tab, only to realize, IT WAS THE EXTENSION PAGE. so...yeah, it doesn't work.

'Export' doesn't work.

A complete waste of time trying to bring back the system theme that Firefox screwed up.
If you want to to something useful allow us to configure the _existing_ theme then not a useless preset

All I wanted to do was change the color of the active tab so I can see it more easily. The second I clicked on that one new color, it changed EVERYTHING, and it looked horrible. I can't remove this add-on fast enough.

hate it have lost hours trying to loose t.

Can't get to page to change anything so at this point, totally useless.

Not very configurable, and the colour picker is extremely primitive.

The writting in the bar uptop are WAY too small ... put some other choices like nature selection and NOT those flashy color that make your head spin ... thank you
