Stop browser freezing and lagging — in one click. Speed Booster for ChatGPT makes massive conversations smooth again by intelligently rendering messages. No more jittery scrolling, no high CPU usage, and zero data collection. If you use ChatGPT for coding, writing, or research or just long chats, you know the problem: once a chat gets long, Firefox slows to a crawl. This extension solves that instantly. 🚀 Key Features

Instant Speed: Makes long threads (500+ messages) feel like new.
Resource Efficiency: Dramatically lowers CPU and memory usage to save battery.
Context Preservation: Keeps your full history accessible without the lag.
Privacy First: Runs 100% locally. No tracking, no uploads.

💎 Boost Your Workflow with PRO While the free version is perfect for most, you can upgrade to PRO for a small one-time fee to unlock unlimited fast chats.

No daily limits: Remove all daily usage limits on the lag-reduction engine for your longest conversations.
Quiet Mode: Work in a completely clean interface by disabling all UI hints and notifications.
Custom Thresholds: Gain full control over exactly how many messages are rendered at once to perfectly match your hardware's power.
By buying PRO, you support the development.

❤️ A Note from the Developer This tool is specifically made to eliminate browser rendering lag (local slowdowns). While I cannot fix OpenAI’s server-side issues, this extension significantly optimizes how your device handles large chats. Please note: I am a solo developer managing this project in my spare time alongside a full-time job. I do my best to keep the code updated and answer most important emails personally. I kindly ask for your patience and constructive feedback as I work to make the tool better for everyone and keep it working as long as possible. If this extension helps save you time, like it does for so many other people, please consider supporting the development by buying a PRO license - it makes a huge difference! If you run into an issue, please contact me via contact@gptspeedbooster.com before leaving a negative review. Constructive feedback helps me make the tool better for everyone! This extension is an independent project and is not affiliated with, endorsed by, or sponsored by OpenAI or ChatGPT.
