This used to be GREAT add-on used by many, many dedicated Firefox users.
To the author: if you do not remove nag screen (begging for money - how can you be so cheap, Firefox is all about free and not getting rich overnight) you will loose all loyal and future customers. No hacker will waste his/her time to patch your code. This is JUST add-on people can live without.
Some other add-ons do suggest that donation is appreciated but not one (at least which I use) is intrusive like yours. SHAME ON YOU!
Currently I am removing it completely. When you change your attitude and fix the code I will put it back. Enjoy your life… alone.
