no restart of firefox possible Rated 3 out of 5 stars

Thanks for this beautiful theme. Unfortunately since I installed it, I´m not able to install anything else, because the restart-function is disabled in the add-on area. I can click it and firefox is closing, but it doesn´t restart... so, i can´t put any other add-on to my firefox-browser.
What can I do?
Thanks a lot for a quick reply!

Problem fixed: :) I deleted the whole theme, so now I can install other add-ons. But of course it would be nice to be able to use it, because it is beautiful.
