Try these steps, in order, until NoScript is working right again.
- If you have any Firefox extensions called HP Smart Web Printing, Skype, .NET Framework Assistant, or McAfee Site Advisor, then uninstall or disable them. They're buggy and known to cause problems with the status bar icon.
- The NoScript settings became messed up somehow. Reset the NoScript Options by pressing Reset at the bottom of the Options dialog. Export your whitelist before doing that if you've added any trusted or untrusted sites you'd like to restore after NoScript is working again.
- There might be an extension conflict. Use the Add-ons manager to temporarily disable any other Firefox extensions you have installed, except for NoScript.
- Perform a
Standard Diagnostic. If NoScript isn't working by the time you get to the "Create a new profile" step, a new profile with no other extensions besides NoScript should work right.
Hope this helps. Please let us know whether it does.
