Fix Firefox Blocking Local IP Addresses on MacOS Sequoia

Are you experiencing issues accessing local devices with Firefox after updating to MacOS Sequoia? You’re not alone. Many users have reported that Firefox blocks local IP addresses such as routers, NAS devices, and HomeAssistant servers when using a static IP address over Ethernet. Here's what you need to know and how to fix it.

The Issue

After restarting your Mac running MacOS Sequoia, Firefox may fail to access local network devices. You’ll encounter error messages, even though other browsers like Safari work seamlessly. This problem persists despite the latest updates to MacOS Sequoia.

Quick Fixes

To resolve this issue and regain access to your local devices, try one of the following methods:

1. Reset the Ethernet Connection:

   • Go to System Preferences > Network.

   • Disable the Ethernet connection, then re-enable it immediately.

2. Reconfigure Local Area Network Access for Firefox:

   • Navigate to System Preferences > Privacy & Security > Local Area Network.

   • Toggle Firefox off and then back on.

     
      
     

Why Does Safari Work?

Interestingly, Safari doesn’t experience this issue and provides immediate access to local devices after a reboot. This suggests the problem may be specific to how Firefox interacts with MacOS Sequoia’s network settings.

Additional Tips

• Ensure your Firefox browser is updated to the latest version.

• If the problem persists, consider using Safari or another browser for local network access until Mozilla addresses the issue.

By following these steps, you can minimize disruptions and continue to manage your local network devices efficiently.
