View Full Version : Performance in IE 7 and Mozilla Firefox (any version after 8.0)

15 Jan 2013, 5:25 AM
We developed an application purely based on ExtJS 4.0/4.1, it performs well in Mozilla Firefox(any version after 8.0). It is drastically slow in IE 7. Is it the issue with Ext JS framework?? or do we have any tools which determine why performance is slow in IE and not in Mozilla??
