Far, far, very far outside the purpose of the Mozilla support forum and 99.87 percent beyond the knowledge of the people who visit here. Using duckduckgo or another search engine will / may supply you with additional references. One of the servers in Chicago might be one - it's always involved with the phony FF update malware (in the US anyway.) Unfortunaely, the owners of the servers never want to give out information about their clients, and I'd guess the NSA more so. Your browser wouldn't know (that's why they call it secret.) Implications? Oh, someone might come knocking on your door. The search engines keep track anyway of key words. Wanna get paranoyd? Your router and the TCP/IP addresses dynamically established might be sending data streams to places directly. I know I've seen 6 ports "listening" for messages on my machine. But the government already knows I don't wear boxer shorts. (humor (or is it?)) Unless you get another response here, and if there isn't a black car suddenly parked outside your door, IMO it would be nice if you marked this as solved. But don't give up your quest, just direct it to one of the colored-hat groups for the information you seek.
