Hey everyone.
I’m sharing a practical fix for a frustration I know a lot of us have been dealing with for a long time: once a chat gets long, Chrome/Firefox slows to a crawl.
The Problem:
If you use ChatGPT for coding, deep research or just long conversations, you know the pain: once a conversation hits a certain length, the web UI starts to crawl.
-
Typing lags and text appears seconds after you press keys.
-
Scrolling becomes choppy.
-
It takes forever to see the replies from ChatGPT.
The Root Cause:
- ChatGPT keeps every message rendered in the DOM forever, so after a while your browser is holding thousands of elements in memory. No wonder it chokes..
The Fix:
-
I built a local Chrome & Firefox extension to solve this: ChatGPT Speed Booster
-
It makes huge conversations smooth again by rendering only a configurable amount of messages at a time.
-
You can see older messages simply by scrolling up. (Something I haven’t seen in other people’s attempts to fix this issue)
-
No lost context, no data collection - ever.
-
100% Privacy-first - runs entirely locally on your machine.
-
You keep your full history, but without the lag. It’s simple, but it’s made a massive difference for me.
Community feedback so far
- Many people on Reddit have tried it and left positive comments, many have let me know my extension has made ChatGPT super fast again for their long chats.
How to try it
- Search for “ChatGPT Speed Booster” on the Chrome / Firefox Web Store. It’s completely free. Just install, refresh your tab, and open a long chat to see the difference.
Feedback? If you try it out, I’d love to hear how it runs on your machine. Drop a comment or review if it helped you - that would mean a lot!
