26 Sept. 2011 I get the dialog box mentioned in the Question when I click to open Firefox. I click OK button in dialog box and Firefox opens/launches. I installed Java around the same time I installed Firefox. I installed Firefox and Java within the last seven days. I have a screen shot of the dialog box.

This issue can be caused by the McAfee Site Advisor extension
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.

Firstly I disabled McAfee SiteAdvisor extension found in Extensions in the Add-ons tab. This was a solution to the issue. Problem solved!
Next, I disabled the McAfee ScriptScan for Firefox 14.4.0 as well. Just for the heck of it.
Thank you for the help!
