Speed Booster for ChatGPT is a Firefox extension designed to enhance performance during long conversations. It addresses common issues such as browser lag and high CPU usage by intelligently rendering messages, ensuring smooth scrolling even for lengthy threads. This tool is particularly beneficial for users engaged in coding, writing, or research, where extensive chats can slow down performance. The extension operates locally, prioritizing user privacy with no data collection or tracking.

The free version of Speed Booster is effective for most users, but a PRO upgrade is available for those requiring enhanced features. This includes unlimited usage of the lag-reduction engine, a Quiet Mode for distraction-free operation, and customizable rendering thresholds. The extension retains full chat history without performance degradation and is designed to work seamlessly with OpenAI's servers, making it a valuable tool for optimizing your ChatGPT interactions.
