ChatGPT Speed Booster: Fix Lag in Long Chats Autor: Bram van der Giessen

Stop ChatGPT from freezing and lagging - in one click.

ChatGPT Lag Fixer 2.0 makes huge conversations smooth again by rendering only a configurable amount of messages at a time — no lost context, no data collection, no slowdown.

If you use ChatGPT for coding, writing, research, or long discussions, you know the problem: once a chat gets long, Firefox slows to a crawl, scrolling becomes jittery, and CPU usage spikes.

ChatGPT Lag Fixer solves this instantly.

🚀 What it does
Makes ChatGPT fast again — even in threads with 500+ messages — by rendering only the latest set of messages at first. You can configure exactly how many messages to keep visible!

Older messages are easily restored: just scroll up in your chat and press the "Load more messages" button. This keeps your full chat history accessible without the lag and without losing context.

✅ Why you’ll love it

• Smooth, zero-lag typing & scrolling — even in massive threads
• Lower CPU & memory usage — keeps Chrome fast and extends battery life
• No lost messages — your complete history stays intact
• Works automatically — install once and ChatGPT instantly feels faster

🔒 100% Privacy
Runs entirely on your device.
No data collection, no tracking, no uploads, and no chat deletions — ever.

❤️ A Note from the Developer
This is a free, open-source project developed in my spare time to help the community.
Please note: This extension fixes browser rendering lag (your computer slowing down due to too many messages being rendered). Its not perfect and it cannot fix problems on OpenAI's side or anything else beyond my control.
If you run into an issue, please consider opening a ticket on GitHub before leaving a negative review.
Constructive feedback helps me fix bugs, while kindness keeps open-source alive!
