"Allow the installation of an extension" popup is not displayed

I just installed Firefox 13 on my new laptop, and I try to install lastpass on their site so I chose Windows and I click on the button "Download" in firefox, and I don't get the usual pop-up asking me if I'm hosting the installation of this extension or not... I get the blue puzzle icon in the awesome bar, but I'm not being invited to allow, so I can't install it...

What happens if you click on this icon puzzle on the address bar?

Try turning off hardware acceleration.
