That's not Firefox. Where/how are you getting this error?

Hello andrewvz, You will of course have made sure all the other fields (like State/Province and Country) are filled out (?) Your system details show that you are using a very old Firefox version; as you are using plugins : would you consider updating to the latest Firefox ESR version ? https://www.mozilla.org/en-US/firefox/all/#product-desktop-esr --------------------------------- If that doesn't make a difference, would you try this please : Reload the page : Hold down the Shift key and left-click the Reload button or press 'Ctrl + F5' or press 'Ctrl + Shift + R' Would you try this please :<BR> Clear the Firefox cache :<BR> https://support.mozilla.org/en-US/kb/how-clear-firefox-cache "Remove the cookies" from websites that cause problems :<BR> https://support.mozilla.org/en-US/kb/delete-cookies-remove-info-websites-stored (scroll down to : "Delete cookies for a single site") ---------------------------------------------------------------- If you use extensions like Adblock Plus, NoScript, Flash Block, Ghostery, then always make sure such extensions do not block (wanted) content. You could also check your settings here : https://support.mozilla.org/en-US/kb/enhanced-tracking-protection-firefox-desktop ------------------------------ If none of the above do the trick, then let's try Firefox in Safe Mode : If Firefox is not running : Hold down the Shift key when starting Firefox. If Firefox is running : 3-bar menu => ' ? ' (at the bottom of the dropdown) => 'Restart with Add-ons disabled'. Then OK the restart. A small dialog should appear. Click 'Start in Safe Mode' ( not 'Refresh' !)
