I remember this skin from when I was a kid, when my father was using it for his Firefox. So glad it's still around for my own use!

esta muy bueno, gracias

Muito show

Thème très agréable, qui change de n’importe quel autre qui serait statique.

Afin qu'il fonctionne de façon optimale à chaque redémarrage de Firefox il faut cependant modifié 2 valeurs du navigateur.

Taper "about:config" dans Firefox et accepter l’avertissement.
Ensuite cherché :
- lightweightThemes.persisted.headerURL
- lightweightThemes.persisted.footerURL

Les 2 sont de base sur "True", changer les en "false" avec un double clic gauche ou un clic droit puis "inverser"

Love the color, and the lightning effect. It slows my browser down, otherwise I think this is Awesome!

Cool.

I'll rarely use this, but it'll probably be useful in troubleshooting situations, to show when there's activity in the chrome of the browser whilst content is inactive (or troubled).

i like it

Nice animation indeed, but a bit too frequent in my opinion.
If it freezes, you don't have to install personas-shuffle or whatever. You only have to open about:config (type in "about:config" without the quotemarks in your address bar and hit enter), pass the warning and type "lightweight" in the provided searchbar. Among values shown, find and invert the values of both lightweightThemes.persisted.footerURL and lightweightThemes.persisted.headerURL to false, simply by double-clicking on them. Restart Firefox and now the animation should work without further tweaking.
