Which of the following actions would NOT increase a user's privacy while browsing?

Disabling auto-play of video and audio files primarily affects user experience rather than privacy. This action prevents media from playing automatically when a webpage loads, which can enhance user enjoyment and reduce distractions while browsing. However, it does not directly mitigate tracking or data collection practices that might be employed by websites.

In contrast, using a VPN service encrypts internet traffic and masks the user's IP address, enhancing anonymity online. Clearing browser cache regularly removes stored data from previous browsing sessions, helping to protect information that could be used for tracking. Utilizing incognito mode allows users to browse the internet without saving history or cookies, also promoting greater privacy. Each of these actions contributes specifically to the safeguarding of personal data and privacy while online.
