When I try to click on Add-ons, from the Tools menu, I get this error message of an unresponsive script: file:///C:/Program%20Files/Mozilla%20Firefox/components/nsExtensionManager.js:623. This is to say the least about the unresponsive script errors at other times. However, at all times, it won't go away - even by clicking on the 'stop script' option; even with checking the 'don't ask again' option. I've cleared the cookies and history as best I could, but it appears that there is some sort of conflict. How can I resolve this? Kevin: businesscity@snet.net. Thank you.

This is typically caused by a problem with the Personas Plus 1.6 add-on and it conflicting with the Google toolbar.

Try disabling the Personas Plus add-on. To do this open the add-ons manager by selecting the Tools menu, then Add-ons. In the list of installed extensions click on Personas Plus, then click on either disable or uninstall.

If you can not access the add-ons manager, follow the instructions in the safe mode article to start Firefox in safe mode. You should then be able to disable or uninstall Personas Plus. You can find more information on this procedure in the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article.
