I just installed the latest update to Firefox 4.0.1 and now when I click on a link, a pop-up window comes up. The title bar says Java Script Application and the message has a "!" in a yellow triangle and says uninstal set.

Other users have reported that this is caused by one of their add-ons. I suggest going to the Add-ons page and disabling everything that is not essential, and then restarting Firefox. Hopefully it's not caused by something you really rely on.

orange Firefox button > Add-ons > Extensions

or

Tools menu > Add-ons > Extensions

Any luck?
