Platform-Specific Issues

Mac-Specific Problems

Issue: Extension works on some sites but not others (M1/M2 Macs)

Fix:

  • Update Chrome to latest version (Rosetta compatibility)
  • Or use Chrome Canary (native ARM build)

Issue: Keyboard shortcut conflicts with system shortcuts

Fix:

  • Chrome Extensions → Keyboard shortcuts
  • Change from Cmd+Shift+S to something else
  • Avoid Cmd+Option+[letter] (usually taken by macOS)

Windows-Specific Problems

Issue: Extension not appearing after installation

Fix:

  • Check Windows Defender didn't block it
  • Windows Security → Virus & threat protection → Allow app
  • Or temporarily disable during installation

Issue: High memory usage causing crashes

Fix:

  • 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"
  1. If this fails → API connectivity issue
  2. 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

  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.
