Downloading Extensions? Puntuado con 4 de 5 estrellas

It's a great add-on, works great. But for some reason, when I try to download new extensions with this one enabled, I get an error, unless I bypass my cache (which gets annoying, doing it every time I want another extension). Is there any way to fix this? Am I the only one with this problem?
