I rarely download anything big, but I often go through a large amount of bandwidth by simply browsing around. For example, when I play a YouTube video, click a link, and then return to the video, the whole video reloads. When I read some websites, such as BoingBoing.net or Cnet.com, my status bar shows a whole lot of data being transferred through other domains. Some pages seem to send/receive data at certain intervals for the duration of my visit. When I begin to enter a search in Firefox's search bar, a list of suggestions is automatically downloaded. In addition to this, Firefox often requests internet access of its own accord, even though I have automatic updating turned off. All this is costing me! How do I stop unsolicited use of my internet connection? How do I go about not wasting bandwidth like this?"
