I’ve been rewarded with a cool and most importantly, free Spread Firefox t-shirt by the Team for spreading the word about Firefox a few years back.
Got an email from them in October (at first I thought it was a trick), and the t-shirt were safely delivered last week.
Even though I’m mostly using Safari (on Mac OS X) now, I still recommend my friend on Windows to use Firefox instead of IE. I still favor Firefox over Safari while using Windows.
