In Firefox, click on Tools then go to add-ons. Under the extensions tab, do you have one listed called NoScript?
Or simply right click in Firefox and look for an entry called NoScript. If it's there, move your cursor over it so more options come up. Select "Allow Arcadecontrols.com". That should do it.
If you don't have NoScript, you could have another add-on that blocks scripts from being ran. Perhaps listing all of your add-ons will help us diagnose the issue.
