No, Firefox does not prioritize privacy over speed.

Firefox is a browser that aims to balance both privacy and performance for its users.

Firefox offers various features to enhance user privacy, such as tracking protection, private browsing, and password management. It also allows users to customize their privacy settings and choose from different levels of protection. However, Firefox does not sacrifice speed for privacy. It is one of the fastest browsers available, especially in its Quantum version, which improved its performance by using a new engine and multi-process architecture.
