❓ FAQ

❗ Panel not showing?

If the panel doesn't appear after installation, try these steps:

1. Enable Browser Developer Mode

   • Chrome/Edge: Open chrome://extensions/, enable "Developer mode" at top right
   • Firefox: Open about:debugging, no extra settings needed

2. Check Tampermonkey Settings

   • Click Tampermonkey icon → Dashboard
   • Find LDStatus Pro script, ensure it's enabled (switch is ON)
   • Go to "Settings" → Ensure "Allowed permissions for user scripts" is correct

3. Refresh the Page

   • After completing above settings, refresh Linux.do or IDCFlare page
   • Panel should appear at bottom right

💡 If still not showing, try disabling other potentially conflicting extensions

🦊 Firefox login fails?

Some Firefox users may experience OAuth login failures due to privacy settings (authorization succeeds but panel doesn't update). Try these steps:

1. Check Enhanced Tracking Protection

   • Open about:preferences#privacy
   • If set to "Strict", try changing to "Standard"

2. Check Container Tabs (if using Multi-Account Containers extension)

   • Ensure auth popup and main page are in the same container
   • Or temporarily login in a regular tab without containers

3. Check Third-party Cookie Settings

   • Ensure third-party cookies aren't completely blocked
   • Check in about:preferences#privacy → "Cookies and Site Data"

💡 Chrome, Edge, and other browsers usually don't have this issue

📊 Why isn't reading time increasing?

• The script detects mouse movement, scrolling, clicks, and other activity
• 60 seconds of inactivity will auto-pause the timer
• Timer resumes when activity is detected

☁️ Will cloud sync overwrite local data?

• Cloud sync uses a keep higher value merge strategy
• For the same day, keeps the higher value between local and cloud
• No recorded reading time will be lost

🏪 How to publish listings on LD Store?

1. Open the LDC Credits panel, switch to "LD Store" tab
2. Click "My Listings" → "Merchant Settings"
3. Enter your LDC PID (get from credit.linux.do profile page)
4. Configure notification URL (optional, for order callbacks)
5. Save and start publishing exchange listings
