This is such a usefool tool, I love creating things so this is really fun! It's very easy to use and helps make great quality themes! :D

Works great, uses arcane wizardry to change your theme!

It's a shame that Personas has got retired.
Since I have Firefox Color my Firefox isn't working right anymore. It lags most of the time. Some pages (most of them are pages with shops, like amazon et al) aren't loading or crashing while loading. To avoid other reasons I tried it with several browsers (even the bad IE) and nowhere I have these errors I'm getting on Firefox since I'm using FF Color. And of course I tested it when FF Color was deactivated or removed. Then FF worked proper, like always before and with Personas. So after sending this review I'll say good-bye to it and will search for alternatives. FF Color is none!

Very Good!!!!

Le plugin (presque) parfait pour personnaliser son thème.
Dommage que le fond des pages vides restent blancs.

i completely love this add on, i loved being able to change the simple black and white to a much more nicer color pallet, although i was disappointed to find out that the add on wasn't already verified since it was created by mozilla themselves. maybe they haven't gotten to this add on so it isn't verified just yet. still, i'd appreciate if all the add ons mozilla made themselves were automatically verified
