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.
