firefox tbfill issue

Has anyone had an issue using firefox with ExtJS? I have a component not showing up if it is after a tbfill short cut '->'.

This is in a Toolbar class.



items: [

{

xtype: 'image',

width: 32,

height: 32,

src: 'image.png'

},

{

xtype: 'component',

cls: 'site-title',

html: 'DPM'

},

'->',

{

xtype: 'component',

cls: 'user-info',

html: 'Welcome, ' + driverPerformConfig.userName + ' | <a href="/admin/logout">Logout</a>'

}

]



This only occurs on firefox. Im on version 28.0.
