I'm getting a persistent "JavaScript Application" popup notice that is difficult to close. The problem just started today, and I can't seem to fix it. Any suggestions?
The offending popup reads:
[JavaScript Application]
(yellow triangle with an exclamation point) followed by the words "uninstal set"
Note: the spelling of uninstall is as shown above.

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 in the Extensions category 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?
