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

Stop ChatGPT from freezing and lagging - in one click.

ChatGPT Lag Fixer makes huge conversations smooth again by rendering only the messages currently in view — 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 messages currently visible on screen.
Messages outside the viewport are replaced with tiny placeholders and restored instantly as you scroll, keeping your full chat history accessible without lag and without losing context.

✅ Why you’ll love it

• Smooth, zero-lag typing & scrolling — even in massive threads
• Lower CPU & memory usage — keeps Firefox 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.
