Works well for me. I understand it works online. Takes a second until it uploads my own colors. Good I can add and save my own themes in the custom backgrounds option and can get it back with one click without having to disable Firefox Color. It saves my colors and own themes online, so the share option makes it possible to transfer it to any of my other PC.

Thank you guys, nice job. Experimental but works well. Keep up the good work. I like it.

It's a good idea but it doesn't work well along with themes. It's one or the other. I found it quite limited then. Therefore, I'm back to my usual themes...

this one is perfect. Just please let the user go back to their original theme without having to disable the addon.

Thank you for Firefox Color, my family and coworkers truly love every aspect of this feature. I can see where it would end up replacing a lot of (creative/picky) users’ need for any other published-Firefox-themes. I have been waiting for something like this for forever, to (perfectly) match my overall OS theming - finally. Bravo!

I've changed my review to two stars because Personas Plus is going out of support in six days and this add-on is still very experimental. I need it to be much more user friendly, starting with allowing 10 MB JPG images from my Panasonic LUMIX.

Fantastic tool :) Finally I can change everything.in chrome.css, not everything was possible.Please continue the work, thank you.
edit :Please add sidebar change color background and text, and will be perfect.
