This is a great looking theme. The lightning animation is nice to look at without being intrusive. I think it's pretty much perfect.

But I'm giving this a 1-star rating. I'd give it 0 stars if I could.

I noticed that this theme looked a lot like the Electric Chaos theme, which can be found at https://addons.mozilla.org/en-US/firefox/addon/electric-chaos/. That's because it's identical and this one is the stolen version. The original artist has their work under a Creative Commons license, which means anyone can copy, alter, or redistribute it freely. All anyone has to do is give credit to the original artist. This user did not do that and even has a more restrictive copyright license.

Support the original artist who actually put in the time and effort to create this by using theirs instead: https://addons.mozilla.org/en-US/firefox/addon/electric-chaos/
