This video offers an in-depth demonstration of Firefox's core features and privacy protection upgrades. The presenter details the search engine quick switch functionality in Firefox version 145, allowing users to type '@' followed by a search engine name (e.g., @eBay, @DuckDuckGo, @Perplexity) in a new tab to search directly on different platforms without visiting their websites, significantly boosting operational efficiency. The video highlights the major breakthrough in Firefox's second-stage anti-fingerprinting technology: by blocking crucial data such as font detection, hardware information, processor core count, and multi-touch support, it reduces the risk of unique user identification from 65% to 20%, effectively preventing cross-site tracking even in private browsing mode or when cookies are disabled. The explanation covers the principles of fingerprinting (time zone, GPU rendering, screen resolution, etc.), the importance of default browser protection, and how to customize search engine keywords in settings, making it ideal for users concerned about online privacy, multi-account management, and efficient browsing workflows.
