I get a "Login Failure - User Name Not Found" message

If you used the manual setup and you entered your information incorrectly you would see this message. If you are sure you've entered everything correctly, it could be that you need to update Firefox Home to the latest version. In that case:

• Open the Apple Store app on your iPhone.
• Tap Updates in the lower right hand corner.
• There should be a Firefox Home update available. Tap the Update button to install it.

I get a "Login Failure - Error Retrieving Data" message

If you get this error message, you may not have completely synced your Firefox data before trying to log in to Firefox Home. Using Firefox in Private Browsing - Browse the web without saving information about the sites you visit mode, having Firefox set not to save history or quitting Firefox before it completely syncs for the first time, can cause this error.

If you are using Private Browsing, disable it and follow the steps to Replace your Sync information. Then make sure you wait until Firefox has completely finished syncing your data before trying to log in to Firefox Home.

I get a "Cannot Sync - Failed To Communicate With Server" message

This message usually means that Firefox Home is having trouble connecting to the Firefox Sync server. This may be the result of one of the following:

• You are not connected to the internet. Make sure you're connected to WiFi or in a location with good reception.
• Your WiFi access point or network requires a log in via a website. Some networks may appear to connect but require a log in before allowing in traffic. Open the web site on your iPhone in Safari and log in before trying to log in to Firefox Home.
• Your network is blocking access to the Firefox Sync servers. Please talk to your network administrator.
