Firefox 16 - Norton toolbar Win 8

Im running Windows 8 Pro with MCE and Norton Internet Security 2013 and my toolbar lags when opening/closing vault and even selecting a login. It happening on (2) computers running same versions of everything. I loaded it in FF 16 and IE in Windows 8 it freezes for about 2 mins then finally goes. Any solutions.??

Also BTW: ive disabled the toolbar and the browsers work great, then i re-enable it and it bogs down again so it has to be the toolbar.
