After I had some problems installing the update I just uninstalled and manually reinstalled it. One reason I thought I had a "problem" was because I always had two instances of Firefox running in the task manager. After I get it all set back up I still have a Firefox instance running when it's not open. Anyone else experiencing this? I don't care that it's running in the background but I would like to know what it is doing. I scanned through the Services menu in Computer Management but I saw no mention of Mozilla/Firefox.
