About this extension
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.

🎁 A Special Thank You
As a huge thank you for being an early supporter and giving great feedback, the first 10,000 early supporters across all browsers have been automatically upgraded to PRO for free for their current installations!

🛠 How it Works
The extension renders only the most recent messages to keep your browser fast. Need to see older parts of the conversation? Just scroll up and hit "Load more". Your full history remains safely on OpenAI's servers—we just make it easier for your browser to handle.

🔒 Your Privacy Matters
  • No data collection or tracking.
  • No chat deletions.
  • All trimming logic runs entirely on your device.

🛡️ Transparency & Permissions
To support the new PRO features and integrity checks, the extension requires access to:
  • gptspeedbooster.com: Used for a quick "Integrity Check" to ensure the extension hasn't been tampered with and to verify the extension is not a copy.
  • api.freemius.com: Our secure partner used solely for handling one-time PRO license purchases and account management.

These permissions are strictly for validating PRO licences and weekly integrity checks. All message processing remains 100% local on your machine, and NO personal data or message data ever leaves your device.

❤️ A Note from the Developer
This tool is designed to fix browser rendering lag (your computer slowing down). While it can't fix OpenAI's server issues or anything else beyond my control, it significantly improves your local experience.

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 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!
