I'm now using GNOME Shell 3.5.4 on Ubuntu 12.04.1 Desktop amd64
frederick@Frederick-Pasokon:~$ gnome-shell --version GNOME Shell 3.5.4
When I visit the extensions.gnome.org site, it can normally display the on/off button. And if I slide the button to on, it will pop-up a window to ask me whether I want to install the extension or not.
And after I clicked "yes", just nothing happened. If I press F5, the button resets to off as I've done nothing.
Trying installing some of the extensions will create a folder in ~/.local/share/gnome-shell/extensions. But it's empty without anything inside.
I checked my unzip and it's up-to-date.
Please help me!
