Features & Capabilities

🚀 ChatGPT Message Compressor Make long ChatGPT chats usable again — no more frozen tabs, slow scrolling, or waiting forever for huge conversations to load.

ChatGPT is great, but very long chats can seriously slow down your browser. Big conversations can take ages to open, lag while scrolling, and make the page feel heavier over time.

ChatGPT Message Compressor fixes that by keeping the newest messages rendered normally while compressing older message history locally in your browser. The result is a much faster, smoother ChatGPT experience — especially if you use ChatGPT every day.

📌 Why This Exists Long ChatGPT conversations can become painfully slow.

If you use ChatGPT daily, you’ve probably had chats that start taking forever to open, scroll poorly, or make the tab feel frozen. Sometimes loading a massive conversation can take minutes.

This extension is built for that exact problem.

Instead of forcing your browser to keep rendering every single old message forever, ChatGPT Message Compressor compresses older parts of the conversation so the page can breathe again. Your long chats become usable again, and the time saved adds up fast.

💰 3-day full trial Then upgrade once for lifetime unlimited compression on this browser.

No subscriptions. No recurring fees.

Is ChatGPT Message Compressor Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

ChatGPT Message Compressor requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

ChatGPT Message Compressor is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
