Firefox advises users to disable McAfee plugin

McAfee ScriptScan is causes stability or security problems, Firefox reports

It's the last thing McAfee would want users to hear about one of its products, but the Firefox browser is advising users to disable McAfee's ScriptScan software, saying that it could cause "stability or security problems."

SriptScan ships with McAfee's VirusScan antivirus program. It's designed to keep Web surfer's safe by scanning for any malicious scripting code that might be running in the browser. But according to Mozilla it has an unintended side-effect: It can cause Firefox to crash... a lot.

In a note posted to its website, Mozilla said that the add-on "causes a high volume of crashes," and is "strongly encouraging" users to disable the software. The warning applies to all users of version 14.4.0 and below of the plugin, Mozilla said.

The Firefox browser started popping up warning messages Monday, advising that users disable the software

In McAfee user forums, there is a smattering of complaints about the Firefox problem.

McAfee is aware of the Mozilla issue and is investigating the matter, according to Francie Coulter, a McAfee spokeswoman.
