Firefox themes

'Sup everyone.

So I've been using Firefox for quite a while and I was wondering if you guys know a place where I can easily download specific themes for this browser; something anime/manga related wouldn't be too bad either.

Best way to have nice customizations is to use Firefox Personas. Go check this page: http://www.getpersonas.com/en-US/

Indeed, large variety of choice.

Thanks ;).
