Server seems very slow on browser startup -- takes 3 or 4 seconds to 'load' the colour changes from server, then when finally done it resets the tab to blank even if I've already clicked a bookmark!

Started doing this a couple of months ago following a Firefox update.

Okay. I'm going to state an honest review regarding the Firefox Color extension. While it's very cool that I get to create my own Firefox themes, whether depending on the time of the year or themes based on pop culture, there's one major drawback that's stopping me from giving the Firefox Color extension five stars. Every time I try to test out one of my themes made from Firefox Color to upload to the add-ons after downloading the XPI file, I always get the same error; which is stopping me from sharing my own Firefox themes: "This add-on could not be installed because it appears to be corrupt". I would be much appreciated if you were to update this extension so that you could troubleshoot this issue that I've been having.

This is what I needed. Popup Background on interface, covers color selector.

There should be context menu (right click menu) color customization within the editor.

-[ my context menu looks out of place now :c ]-

I loved this theme for years — until now. When this gets fixed I'll give it 5 stars: it suddenly happened today that the webpage where you customize the colors is completely wonky. The entire page is in black & white, no color; the template is merely black broken outlines; the list is unworkable; and the color palette doesn't exist except for the hex numbers. Please please fix! Thank you.

Крутое расширение!

BROKEN - exported themes can't be installed - both .XPI and .ZIP - instalation says that add-on is broken. Tested many times, FF on Win 10 and Debian. Release and ESR. Please fix it - theme from FF Color can't be synced without instalation, the theme is broken on PC without straight source (non-synced doesn't work).

Best browser extension I've ever used! Beautiful! Works great! A lot of choices but easy. Can be time consuming depending on amount of customization's you want to make. I love customizing and detail this extension almost has it all. I do wish an element could be added for an image/wallpaper to the background and a microphone icon/voice search in Firefox search bar so that I could used Firefox Default Homepage again. Thanks

creating a theme is easy; HOWEVER, trying to select a saved theme is literally impossible because of the popup preview. The popup preview literally covers the saved theme tab, and the only way to access it is by saving another theme. it's got some jank, and i wish you could edit or crop and reposition your photos, but it's fairly easy to use.

Amazing addon
