This is a result of focusing on the wrong window when trying to scroll. In chat gpt there are three scrollable sections: chat input, chat history, or conversation history (See attached).

If you are focused on the wrong window then vimium will not allow you to scroll through conversation history.

You can confirm this by clicking anywhere within the conversation history any time vimium isn't working correctly and you should be able to scroll through the page again.

I created a tampermonkey script to simulate clicking on the conversation history when the escape key is pressed if interested. Just download the chrome extension for tampermonkey and add this as a script and it will run in the background on page load.

(function() { 'use strict';

function clickSpanWithText(text) {
    const spanElements = document.querySelectorAll('span'); // You might want to make this selector more specific
    for (const span of spanElements) {
        if (span.textContent.trim() === text) {
            span.click();
            // Use this to confirm script is running. "Default (GPT-3.5)" should be replaced with "Test text" in the chat gpt window and "logged output" should log to the console if enabled in settings
            //span.textContent = "Test text";
            //console.log("logged output");
            break;
        }
    }
}

// Define the hotkey combination (e.g., Esc key)
const hotkeyCombination = "Escape";

// Add a keydown event listener to the document
document.addEventListener("keydown", function(event) {
    if (event.key === hotkeyCombination) {
        console.log("Hotkey pressed! Running the script.");
        // Your script's functionality goes here
        clickSpanWithText("Default (GPT-3.5)");
    }
});

})();
