Notes

I built this extension since I got tired of sending premature prompts to claude.ai by accidentally pressing Enter while typing in their chatbox.

All I need is a temporary textarea where I can write whatever I want with basic markdown syntax support, then copy and paste it to claude.

I do not think I will add new features in the future.

• I built this using Claude Opus 4.5.
• This is the first Firefox extension I have ever built.
• Feel free to use this as you like.
