Console Logger - Browser Extension
A powerful Chromium browser extension that captures JavaScript console messages (log, warn, error, info) from any active tab, displays them live, and automatically saves them to a text file.
Key Features:
- Full Console Capture: Uses chrome.debugger API to catch all messages, including native browser errors that content scripts miss.
- Deep Object Logging: Captures nested objects, arrays, and stack traces — not just string representations.
- Live Monitoring: Real-time display of logs in the popup window.
- Auto-Save: Periodically saves captured logs to your Downloads folder without prompting.
- Custom Save Location: Choose where to save your logs with a file picker.
- Smart Overwrite: Updates the same file (console-logs.txt) continuously, preventing file clutter.
- Persistent Storage: Logs are stored locally and survive browser restarts.
- Cross-Platform: Works on Windows, macOS, and Linux.
How to Use:
1. Navigate to the website you want to debug.
2. Click the extension icon to open the popup.
3. Click "Start Capturing".
4. Important: Your browser will show a warning banner: "Console Logger started debugging this browser". This is a security feature of the Debugger API.
Monitoring Logs:
- Logs appear immediately in the dark-themed console area.
- Messages include timestamps and log levels.
- Objects are serialized with full depth (configurable).
Using Auto-Save:
1. Check the "Enable Auto-Save" box.
2. Set the Interval (default 30 seconds).
3. Set a Filename (default console-logs.txt).
4. The extension will silently overwrite this file in your Downloads folder.
Set Custom Save Location:
1. Click "Set Save Location" to open a file picker.
2. Choose your preferred folder and filename.
3. The extension will display where logs are being saved.
Important Usage Note:
- You cannot capture logs from browser internal pages (chrome://, edge://, about:, etc.).
Data Privacy:
Console Logger stays 100% on your device. No data is sent to external servers. It is strictly a local developer tool.
