About Timestamp Injector for ChatGPT
# Timestamp Injector for ChatGPT
A browser extension that automatically injects customizable timestamps into ChatGPT conversations. It displays the exact time each message was sent or received, directly below the message bubble.
## Features
- **Automatic Injection**: Timestamps are automatically added to all messages (user and AI) in a ChatGPT conversation.
- **Customizable**: Click the extension icon to customize the appearance of the timestamps:
- **Color**: Choose any color for the timestamp text.
- **Font Size**: Select between Small, Medium, and Large.
- **Format**: Choose how the date and time are displayed (e.g., full date and time, short date, or just time).
- **Seamless Integration**: Matches the native look and feel of ChatGPT.
- **Cross-Browser Support**: Works on Chrome, Edge, and Firefox.
*Note for Firefox users: Due to a long-standing Firefox extension bug regarding native color pickers in popups, the custom color picker is disabled on Firefox. Only the preset colors are available.*
