Many programs want to send usage statistics, error logs, and crash reports — data about how you use the application and what problems occurred — to their servers. Some people disable these options, but should you?
I'd be quite happt to allow Mozilla to collect crash data but I wouldn't extend that trust to Google who are commercially obliged to gather as much personal data as possible.
I always send data. Why? I always put in fake data (spam e-mail, name Harry Potter, and stuff).
I do not allow any program to send error reports or Stats back. That is no ones business but mine.
Trust no one - Be very careful
