• Increase virtual memory if < 8GB RAM

Linux-Specific Problems

Issue: Extension not installing on Linux builds

Fix:

• Use Google Chrome (not Chromium)
• Or verify extension sync is enabled
• Check ~/.config/google-chrome/Default/Extensions/

Issue: Permission errors on save

Fix:

• Check file system permissions
• Run:

  chmod -R 755 ~/.config/google-chrome/

Browser-Specific Fixes

Chrome/Chromium Issues

Conflicting extensions:

Common conflicts:

• Other Notion clippers (disable duplicates)
• Ad blockers blocking API calls (whitelist notion.so)
• Privacy extensions blocking scripts (add exception)

Fix:

1. Disable all other extensions temporarily
2. Test if saving works
3. Re-enable extensions one-by-one to identify conflict

Brave Browser Issues

Issue: Shields blocking extension functionality

Fix:

1. Click Brave Shields icon
2. For notion.so: set Shields DOWN
3. For extension permissions: Allow all

Issue: Fingerprint blocking

Fix:

• Settings → Shields → Advanced
• Change fingerprint blocking to "Standard"

Edge Browser Issues

Issue: Extension from Chrome Web Store not working

Fix:

• Install from official Edge Add-ons store instead
• Or enable "Allow extensions from other stores"

Issue: Sync issues between devices

Fix:

• Edge Settings → Profiles → Sync → Extensions (enable)
• Or set up Edge account if not using one

Network & Firewall Issues

Corporate Network Problems

Symptoms:

• Works at home but not at office
• Intermittent connection failures
• "Network error" messages

Diagnosis:

1. Check if notion.so is accessible
2. Test on mobile hotspot (bypasses corporate firewall)
3. If works on hotspot → firewall issue

Solutions:

1. For IT admins: Whitelist these domains:

   • *.notion.so
   • api.notion.com
   • *.notion-static.com

2. For users: Contact IT with this request

3. Workaround: Use mobile app or personal device for clipping

VPN-Related Issues

Issue: Extension stops working when VPN connected

Fix:

1. Whitelist Notion domains in VPN split tunneling
2. Or disconnect VPN temporarily for saving
3. Or use VPN with better compatibility

Issue: Slow saves or timeouts

Fix:

• Switch VPN server (choose geographically closer)
• Use WireGuard protocol instead of OpenVPN
• Upgrade VPN plan for better speeds

Permission Issues

Extension Not Accessing Pages

Issue: "Click to enable on this site"

What it means: Extensions defaulted to click-to-run mode.

Fix (permanent):

1. Right-click extension icon
2. "This can read and change site data"
3. Select "On all sites" or "On [specific site]"

Issue: "Extension cannot access this page"

What it means: Chrome Web Store, settings, or restricted pages.

Reality check: Extensions can't work on:

• chrome:// URLs
• Chrome Web Store pages
• New Tab page
• Some Google services

Workaround: Copy content to temporary document, save from there.

Notion OAuth Connection Issues

Issue: "Failed to authenticate"

Fix:

1. Clear cookies for notion.so specifically:
   • Settings → Privacy → Cookies and site data
   • See all site data → Search "notion"
   • Remove all
2. Log into Notion fresh
3. Reauthorize extension

Issue: "Token expired" or similar

Fix:

• Extension automatically refreshes tokens
• If failing: disconnect and reconnect account in extension settings

Data & Sync Issues

Saves Not Appearing in Notion

Check these:

1. Right workspace?

   • Check workspace selector in extension
   • You might have multiple Notion accounts

2. Right page/database?

   • Verify target page in extension settings
   • Search Notion for the save (might be in unexpected location)

3. Sync delay?

   • Wait 30 seconds, refresh Notion
   • Check "All Updates" in Notion sidebar

4. Quota exceeded?

   • Free tier: 30 saves/month
   • Check usage in extension popup
   • Upgrade or wait for next month

Duplicate Saves

Issue: Same content saved multiple times

Cause: Clicking save button repeatedly during lag.

Fix:

• Wait for confirmation before clicking again
• Check "Saving..." indicator
• Use CMD+Z / CTRL+Z to undo duplicates in Notion

Prevention:

• Enable "Show save confirmation" in settings
• Practice patience during slow network conditions

Lost Formatting

Issue: Saved content doesn't preserve formatting

Common causes:

1. Website uses complex formatting: Notion can't represent all HTML
2. Code blocks not detected: Manually format as code in Notion
3. Tables broken: Notion tables have limitations

Workarounds:

• For code: Select as code before saving
• For tables: Save as text, reformat in Notion
• For images: Save separately, insert manually

Performance Issues

Slow Saves

Normal save time: 1-3 seconds Slow save: 5+ seconds

Causes & fixes:

Large content (> 10,000 words):

• Break into smaller chunks
• Save summary instead of full text

Many images:

• Images upload individually (adds time)
• Save text first, images later if needed

Slow internet:

• Check connection speed
• Use wired connection if possible
• Save drafts locally first

Notion server load:

• Check status.notion.so
• Try during off-peak hours (avoid Monday mornings US time)

High Memory Usage

Issue: Chrome using excessive RAM after installing extension

Diagnosis:

• Chrome Task Manager (Shift+Esc)
• Find extension in list
• Check memory usage

Acceptable: < 100MB Excessive: > 500MB

Fixes:

1. Restart browser (clears memory leaks)
2. Update extension (bug fixes)
3. Disable extension when not actively researching
4. Close unused tabs

Extension Causing Browser Crashes

Rare but happens:

Immediate fix:

1. Boot into Safe Mode: Chrome → More tools → Extensions
2. Disable extension
3. Restart Chrome
4. Check if stable

If stable without extension:

1. Report bug to developer
2. Include Chrome version, OS, crash logs
3. Wait for update

If still crashing:

• Other extension or Chrome bug (not related)

Advanced Troubleshooting

Developer Console Debugging

For power users:

1. Right-click extension icon → "Inspect popup"
2. Check Console tab for errors
3. Common error patterns:
   • CORS errors: Server configuration issue
   • Network errors: Connection problem
   • Permission errors: Authorization issue

Checking Extension Files

For developers:

1. Navigate to:

   chrome://extensions/

2. Enable Developer Mode
3. Find extension → Details → "View in folder"
4. Check manifest.json for correct permissions
5. Look for file corruption or missing files

Testing API Connectivity

Manual API test:

1. Get Notion API token from extension settings
2. Use curl or Postman:

curl -X POST https://api.notion.com/v1/pages \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Notion-Version: 2022-06-28" \
  -H "Content-Type: application/json"

3. If this fails → API connectivity issue
4. If this works → extension bug

When to Reinstall vs. When to Wait

Reinstall if:

• Error messages mention corruption
• Extension icon is missing/broken
• Tried all basic fixes without success
• Last resort before contacting support

Wait/Don't reinstall if:

• Notion server status shows issues
• Problem is intermittent (suggests external cause)
• Just updated extension (give it time to stabilize)
• Corporate network blocks extensions

Prevention Best Practices

Keep extension working smoothly:

1. Regular Chrome updates: Weekly check
2. Don't hoard tabs: Close unused tabs (reduces conflicts)
3. Stable internet: Use wired when possible for critical work
4. Backup important saves: Critical content → copy to notes first
5. Test after Chrome updates: Try one save after each update
6. Monitor usage: Track saves-per-month (avoid quota surprises)

Getting Help

Before contacting support:

Document:

• Chrome version
• Extension version
• Operating system
• Exact error message
• Steps to reproduce
• Sites where it fails

Contact options:

1. Extension support email: Fastest for bugs
2. Chrome Web Store reviews: Public issues (check if others have same problem)
3. Community forums: Other users' workarounds
4. Notion support: If Notion API is confirmed issue

Typical response times:

• Critical bugs: 24-48 hours
• Feature requests: Weeks
• General questions: 48-72 hours

Emergency Workarounds

When you need to save RIGHT NOW:

Method 1: Screenshot + OCR

1. Screenshot content (Cmd+Shift+4 on Mac, Win+Shift+S on Windows)
2. Use OCR tool (macOS Preview, Windows PowerToys)
3. Copy text
4. Paste in Notion

Method 2: Email to Notion

1. Copy content
2. Email to your Notion email address
3. Process from email later

Method 3: Temporary document

1. Paste content in Google Doc
2. Process once extension is working
3. Copy to Notion in batch

Method 4: Browser's reader mode

1. Enter reader mode (if available)
2. Copy cleaner text
3. Paste directly in Notion

The Nuclear Option: Complete Reset

Last resort (10 minutes):

1. Export your Notion data (Notion Settings → Export)
2. Uninstall extension completely
3. Clear all Chrome data: Settings → Advanced → Reset
4. Restart computer (clears all caches)
5. Reinstall Chrome (if truly desperate)
6. Reinstall extension
7. Sign into Notion
8. Test

Only do this if:

• Everything else failed
• You've backed up data
• You have time for complete reconfiguration

Success Metrics

Your extension is healthy if:

• 95%+ successful saves
• Save time < 3 seconds average
• No crashes in past week
• Memory usage < 150MB
• Can save from 90%+ of sites you visit

Your extension needs attention if:

• < 80% success rate
• Frequent error messages
• Regular crashes
• Slow saves (> 5 seconds)
• Missing from toolbar unpredictably

Moving Forward

After fixing:

1. Test thoroughly: Try 10 saves from different sites
2. Note the fix: Document what worked (for next time)
3. Monitor performance: Watch for return of issues
4. Update systems: Keep browser and extensions current
5. Have backup method: Always have plan B for critical work

👉 Install Fresh if Needed - Clean installation often solves persistent issues.
