No Idea what you asking for?

It's a neat trick to perform, but it's a terrible idea. I was under the impression it would change each tab to it's respective web page background, so I could quickly spot which tab to switch to. Instead of changing the entire theme of Firefox, just change individual tab colors. That would be a great idea. I'm coming back to update my rating as soon as that update takes place.

Doesn't work well. Nobody wants more white on their screen.

This did not function or perform as I expected or understood it to. I *wanted* for a website's color to be picked up by this extension and show translucent color. Instead all it did is turn every theme I installed into black tabs, black URL bar, black UI. Polar opposite of what I wanted. Clearly i must show "user error" but in which case you didn't do a good job at all of explaining the effect, nor show any examples. Now all I've been trying to do is remove and DELETE with prejudice since I cannot find its controls anywhere, I can't find it in my browser history. Sorry, I vote poor user experience design, even though everyone else seems to love it.

Very cool, but makes pages load slower.

Using it on Firefox for Windows it didn't work well, for me it only worked on the bet365 site, the only other one that changed was youtube, but it was in a light pink tone with white fonts, in the end I couldn't see anything.
