I've had this theme installed for awhile it reminds me of this pink and purple dual sided blanket I had in my childhood. Opened up Firefox today it was gone and I was really upset. Glad I ended up finding it again :3

Sparkly, cool.

I must say that this add-on is very pretty. However, it just missed the 5 star rating because text becomes a little more tedious to decipher towards the right of the screen. On the other hand, I do acknowledge that to maintain such an aesthetic image, the right side has to be sacrificed. As such, this theme has been delivered 4 stars.

Beautiful!
