Traffic fingerprinting is a technique used to sniff the web traffic by analyzing the data packets’ flow pattern- without removing the encryption. This technique has been recently used successfully to break the layers of anonymity of the Tor network users and hidden services.
Tracking is one of the things that Internet users are exposed to no matter where they go. Websites use analytics software to track them, advertising companies use tracking to make more money because of targeted ads, and social media sites too may know where you have been almost at all times because of buttons and scripts that are installed on the majority of websites.[...] One option that Firefox users have for that is the Firegloves extension. It has not been updated in a year but it is still working fine. It changes settings to common values so that your browser's fingerprint turns out to be less unique than it actually would be without.
