If you are using KDE Desktop, you can make Firefox Windows to be initially opened being minimized. That made my day to me regarding this problem. Just do the following:

1. Open Firefox
2. Click on the Firefox icon on the top left corner of the menu bar -> Advanced -> Special Application Settings...
3. Go to the "Size & Position" tab.
4. Click on "Minimized" and choose "Apply Initially" (YES).

These settings will apply for new Firefox windows from now on and you will not be bothered with pop-ups anymore when running tests with Webdriver.
