Step-by-step troubleshooting flow quick-start checklist
- Confirm baseline connection
- Disconnect Mozilla VPN, then test your internet. If it’s slow or dropping, fix your base connection first modem reboot, contact ISP if needed.
- Reconnect with a fresh session
- Open Mozilla VPN, reconnect to a different server, and give it 30–60 seconds to establish.
- Check for app updates and OS updates
- Ensure both the app and your device OS are current.
- Verify DNS settings
- Ensure Mozilla VPN is handling DNS or switch to a trusted DNS like 1.1.1.1 or Google DNS and test.
- Examine firewall and antivirus
- Temporarily disable firewall or antivirus to see if they’re blocking the VPN. Re-enable with exceptions if needed.
- Review device-specific quirks
- Windows: disable IPv6 for some networks if you notice issues; macOS: check Profile or VPN configuration for conflicts.
- Test with and without IPv6
- If IPv6 causes issues, disable it in device settings or within the VPN configuration as applicable.
- Try split-tunneling or full-tunnel mode
- If available, switch to split-tunneling to limit traffic through the VPN, or use full-tunnel for all traffic for reliability.
- Check for service outages
- Look for Mozilla VPN status on social feeds or status pages to confirm a service-wide issue.
- Reinstall if necessary
- As a last resort, uninstall the app and reinstall a fresh copy.
Configuration tips for better reliability
- Use recommended defaults
- Let Mozilla VPN manage DNS unless you have a specific reason to override it.
- Enable Kill Switch if you need to prevent leaks if the VPN drops.
- Server selection strategies
- If streaming or gaming, pick servers optimized for your region or those with the lowest latency.
- For secure browsing, choose a server with strong performance metrics in your location.
- Protocol considerations
- If available, try different protocols WireGuard is common and fast; OpenVPN can be more stable in some networks.
- Auto-reconnect and startup behavior
- Enable auto-reconnect on startup so you’re protected as soon as you connect to the internet.
- Battery and performance
- On mobile devices, monitor battery impact and adjust to a lighter mode if needed.
Common issues and targeted fixes
- Connection drops or intermittent disconnects
- Change server, switch protocol, restart the app, disable conflicting apps, check for firewall interference.
- VPN shows connected but no traffic
- Verify DNS is routing through the VPN, disable IPv6 if causing leaks, test with a different server location.
- Slow speeds
- Move to a nearby server, check your baseline internet speed, ensure you aren’t throttled by your ISP, disable QoS rules if they’re adversely affecting VPN traffic.
- DNS leaks detected
- Ensure VPN DNS settings are enforced, flush DNS, or switch to a different DNS provider within the app.
- Applications fail to load or stream buffering
- Switch servers, enable or disable split-tunneling depending on needs, check for bandwidth-heavy tasks on the same network.
- Platform-specific tips
- Windows: Run as administrator for initial setup; macOS: ensure you’ve granted the VPN permissions; Android/iOS: test on both Wi-Fi and mobile networks to compare behavior.
Network and security considerations
- Data privacy and logs
- Mozilla VPN emphasizes a no-logs stance; verify what is stored in your region and how it’s handled under law.
- Kill Switch behavior
- If enabled, it should prevent data leaks if the VPN disconnects; test by disconnecting the VPN mid-use and ensuring traffic stops.
- DNS privacy
- DNS requests should route through the VPN; test with DNS leak tests available online.
- Public Wi-Fi safety
- Always use VPN on public networks; it’s the prime scenario for securing sensitive data.
Troubleshooting by device quick guides Understanding Site to Site VPNs: Understanding Site to Site VPNs for Secure Remote Networks
- Windows

- Android
- Clear VPN app cache, test on another network, check battery optimization settings which might block background activity.
- iOS

- Latency changes
- Latency can increase by 20–80 ms depending on the route; closer servers usually reduce latency.
- Reliability indicators
- Look for consistent connect times under 5–15 seconds and minimal packet loss in speed tests.
Advanced tips for power users
- Use split-tunneling for selective protection
- Route only sensitive apps through the VPN to preserve performance for streaming or gaming.
- Manual DNS configuration
- Some power users prefer dedicated DNS resolvers; ensure no leaks by testing after each change.
- Automation via scripts
