Add basic keyboard support to the AI Chatbot sidebar (Enter to send)

[roozjunk]

I really appreciate that Firefox now includes an AI Chatbot in the sidebar. It’s very convenient for quick questions while browsing.

However, the current design has a serious usability issue. You cannot send a message using Enter, which is the standard in nearly every modern chat interface. There is no keyboard shortcut to submit a message at all. The only option is to click the Send button manually with a mouse or pointer.

This breaks user expectations and disrupts natural typing flow. It is especially frustrating for people like me who rely on muscle memory after years of using tools like Slack, Discord, and even basic web forms where Enter submits your message. Calling this a "chat" but removing the most common chat behavior is misleading.

It also creates an accessibility barrier for people with motor disabilities, users who depend on keyboard-only navigation, and power users who rely on speed and efficiency. This lack of keyboard support makes the feature harder to use than it needs to be.

Please consider updating the sidebar so that Enter submits a message, and Shift + Enter creates a new line. That small change would make a huge difference in usability and accessibility.

Thanks for all your work on Firefox, and I hope this feedback helps.

As of 07 June 2025, I don't this issue with Mistral and Gemini. Only ChatGPT has this issue for me from what I've tried.
