i am sorry, i do not want to discourage the programmer, but i doubt the whole idea... something so simple , like setting colors in a software should be integrated offline in the program itself. while genious makers like decentraleyes make it possible to load needed code from local instead of dozens online sources, we now ping the cloud to set a color ? why should i visit hxxx://color.firefox.url to do this ?
Mozilla! What are you doing, you are about to crush your reputation entirely... i thought you care for security, but now we shout to the web, user x has clicked this button.. and he browses in pink, and his ip is ...... ! yay... well done....

i never asked for this extension to be installed on my browser

Super, sauf quand on veut importer un ancien thème dedans pour l'éditer : c'est tout simplement impossible, il faut se retaper l'ensemble des choix un par un.

Exported themes cannot be used in Firefox. Attempting to import them produces an error message.

Export function outdated, won't work for Addons Marketplace

The .xpi file still uses manifest v2, which is no longer accepted. This causes errors like “incomplete theme”. Mozilla hasn't updated this export feature even though v3 has been required for a while.

Installed hoping it would enable changing color of parts of my chosen theme like text or icons, but whatever change you set, just overwrites the theme you chose with the ones from the extension. What's even worst is that the "revert all" button completely removes the theme, while the chosen one still shows as "enabled", so you have to first disable it enad then enable it again.

this causes the bookmarks to be extremely slow in edit adding due to the popup loading the style newly each time it seems.

Exported themes can't be installed (add-on is broken).
Firefox Color can't be synced without instalation.

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.

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).

Tried to upload my Theme (Used the top bit of some old Destiny 1 Promo Art that was shades of blue with white specks) so others could use it, but it was removed in only 11 minutes for and I quote "Content, specifically Spam: This item has been identified as deceptive, high-volume commercial content which is not permitted by AMO."

There are plenty of other Themes that use Destiny as well as other game IPs. I only tried to upload one that I felt looked good that wasn't similar to any others that I could find and yet it didn't even last 11 minutes.

That said, the Extension itself is good and works well. Just don't try to upload anything for others to use apparently.

ruined my browsing experience, might have to go back to chrome because wtf is this??? don't know how to fix this glitch uninstalled app, uninstalled & reinstalled firefox...still the same

This add-on deserves minus stars. As other users state, you can't restore your old theme. This add-on is an absolute RUBBISH!

unable to add transparency to almost all items. this limits your custom imagery to a very limited area, minimizing the entire point of the exercize.

Functionally unusable if you just want to tweak the colors of the standard theme. If I change the color if a single thing, it changes the colors of everything to the stupid theme the add-on starts off with.

I had a custom theme saved & it still shows that it's there, but it won't actually allow it to be put on my screen. I HATE the preset ones as I can't see them well at all & some literally make me physically ill. I NEED to be able to keep the one that I have had for a long time that suddenly disappeared.
