Mozilla Blocks McAfee ScriptScan For Firefox

Mozilla has blocked McAfee’s ScriptScan add-on for Firefox due to performance issues. This add-on was causing lots of crashes for the Firefox users, and Mozilla had to disable it to save users from possible crashes and slowdown.

McAfee’s ScriptScan is a part of its paid antivirus application, which get installed as browser plug-in for Firefox & IE, and scans web pages for possible malicious scripting codes. Hence it saves users from possible threats and scripting attacks. Unfortunately, this plug-in slows down Firefox and causes crashes. Mozilla describes this problem: “This add-on causes a high volume of crashes.”.
