To troubleshoot the printer software update on your Windows 10 desktop, we first need to distinguish between the built-in Firefox Browser VPN and the standalone Mozilla VPN app, as they are managed differently. ​1. Is Firefox VPN Running? ​You can tell by looking at your Firefox browser: ​The Icon: Look for a shield or key-like icon in the top-right toolbar of your Firefox window. ​The Color: If the icon is highlighted/colored, the VPN is active. If it is grayed out or has a slash through it, it is off. ​2. How to Turn It Off or Pause It ​Option A: The Built-in Browser VPN (Most Likely) ​If the VPN is built into your browser, it only protects Firefox traffic. ​Click the VPN icon in the top-right toolbar. ​In the panel that opens, toggle the switch to OFF. ​To Pause: Firefox doesn't have a "timer" pause button, so you will need to remember to toggle it back ON after your 2-3 hour printer update is complete. ​Option B: Standalone Mozilla VPN App (System-wide) ​If you have a separate application installed on your Windows 10 taskbar (near the clock): ​Open the Mozilla VPN app from the Start menu or the system tray. ​Click the large Center Button to disconnect. ​Check for "Pause": Some versions of the standalone app (like NordVPN or similar) offer a "Pause for 1 hour" feature. If Mozilla VPN doesn't show this, simply leave it off until the printer update finishes. ​3. Conflict with ESET Antivirus ​Since you mentioned ESET, it is possible that ESET’s own Firewall is what’s blocking the printer update, rather than the VPN. ​Quick Test: If turning off the VPN doesn't fix the printer update, right-click the ESET icon in your system tray and select "Pause Firewall (allow all traffic)" for 30 minutes to see if that allows the update to go through. ​Summary Checklist for your Printer Update: * ​[ ] Turn off VPN (via Firefox toolbar or the app). * ​[ ] Check ESET (ensure it isn't blocking local network discovery). * ​[ ] Run Printer Update. * ​[ ] Re-enable VPN once finished.
