Enable Do Not Track in Thunderbird

When you open email messages in Mozilla Thunderbird, they may contain embedded HTML web content. Opening of this HTML content is same as opening a webpage in a web browser. This means that some of servers hosting this HTML content may track your online behavior. Fortunately, Mozilla Thunderbird allows you to enable the do-not-track feature which sends a request to all the servers not to track your online activity. Here is how you can enable do-not-track feature in Thunderbird:

  1. Open Thunderbird email client. Press the Alt key once to display the menubar in Thunderbird.
  2. Select Tools → Options from the menubar. This would open the Options window for Thunderbird.

  4. Click on the OK button to save the setting. Now Thunderbird would send a request that you wish not to be tracked by different servers. However whether the request would be honored or not depends entirely on the tracking web servers.
