Firefox just distracted me with another distracting pop-up ("Add this site to your taskbar") about a feature that I don't want to be distracted by right when I was overcoming distractions to attempt a task which I didn't want to be distracted during.
Because I don't need to be distracted (1) I really wish Firefox did not distract me by showing distracting pop-ups advertising distracting features that I don't want to be distracted by or (2) if all of these distracting pop-ups had a checkbox which was 100% effective letting me opt-out of future distracting pop-ups or (3) for christ's sake just put some freakin' timeout so that these only show up after 5 minutes of use so they don't pile on to you the moment you're trying to do something.
