One of the very best themes for FF Rated 5 out of 5 stars
This is one of the best, and it's probably the most thorough skin available. The depth of customization is immerse with almost every UI element getting its treatment unlike the majority of the more shallow efforts. I figure it even supplies special toolbar icons for some extensions like scrapbook. This theme is also very stylish and features excellent UI icons and features.
The two important things I didn't like concern tab skinning. First, it treats text color on tabs to a shade of grayish significantly reducing legibility. Second, it doesn't make friends with the vertical tab bar in Tab Kit. Some themes are at the least tolerable when tabs are vertical, but this one is strictly hard wired for horizontal tabs which totally ruins its style when going vertical.
5 stars for the amount of effort, though I hope vertical tabs will be better supported in the coming releases.
