why is script error coming up on firefox

Internet is running slow when having a number of websites open. Happens for both IE and Firefox but I am mainly in Firefox

Examples of errors are shown below. Any ideas what is causing this or changes I should make.

Script: resource://gre/modules/addons/XPIProvider.jsm -> jar:file:///C:/ProgramData/McAfee%20Security%20Scan/Extensions/%7Be4f94d1e-2f53-401e-8885-681602c0ddd8%7D.xpi!/bootstrap.js -> resource://gre/modules/commonjs/toolkit/loader.js -> resource://gre/modules/commonjs/sdk/loader/sandbox.js -> resource://skype_ff_extension-at-jetpack/skype_ff_extension/data/mutation-summary.js:431

Re: why is script error coming up on firefox

Hi

I would suggest trying the below steps

A) Re-Register JScript Dlls


             To manually register the scripting components on your computer, use one of the following sets of steps,

             If you are running a 32-bit version of the Windows operating system
  1. Click Start, click Run, type cmd, and then click OK.
  2. Type regsvr32 %systemroot%\system32\vbscript.dll, and then press ENTER.
  3. Type regsvr32 %systemroot%\system32\jscript.dll, and then press ENTER.
              If You are running a 64-bit version of the Windows operating system,
  1. Click Start, click Run, type cmd, and then click OK.
  2. Type %systemroot%\system32\regsvr32 %systemroot%\system32\vbscript.dll, and then press ENTER.
  3. Type %systemroot%\system32\regsvr32 %systemroot%\system32\jscript.dll, and then press ENTER.

B) Disabling Skype Add-on/Extension.

Re: why is script error coming up on firefox

You've got McAfee's Security Scan Plus running - or at least present - on your system. If you have any other McAfee product you don't need Security Scan Plus. That little program will keep checking your browser history, but shouldn't slow you down; however, it might be interacting with something else. Best to uninstall it and see if makes a difference.
