looks great but I cant seem to get "Specify a colour" to work, got it to work on one site but idk if its a bug or I am doing it wrong somehow

Easily one of the best add-ons. Turns Firefox into one of the most beautiful browsers in the market.

perfect, just like safari :)

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.
