It sounds like your firewall might be blocking Firefox from accessing the internet, which could be why you're seeing that message when trying to use Shopify. Here’s what you can try: Check your firewall settings – If you're using Windows: Go to the Start Menu and type Windows Defender Firewall. Click "Allow an app through firewall". Look for Firefox in the list and make sure it's allowed for both Private and Public networks. If it’s not there, click "Allow another app" and add Firefox manually. Temporarily disable your firewall/antivirus (just to test) – If Shopify loads after that, you'll know the firewall is the issue, and you can re-enable it and adjust settings accordingly. Try another browser – If Firefox keeps getting blocked, try accessing Shopify using Chrome or Edge to confirm whether it’s a browser-specific issue. Let us know what you find—happy to help further!
