Extjs is cool; but very slow on firefox !
(sorry for my poor english)
I test ExtJS and it's very good... Grid and EditorGrid are very good tools. And on Internet Explorer 6 or 7 , it's rapid.
BUT on firefox (all versions), it's very slow ! Normal or it's a know problem ?
Thanks for your responses.

it's weird cause for me it's the opposite.
very fast on Firefox, medium speed on IE7 and laggy on IE6....-->

Ok thank you.
With firebug disabled and webdevelopper disabled on firefox.. it's rapid. Not too rapid than Internet Explorer but it's correct.
Thank you, ExtJS is very RooooOOoox !!-->

Will this be fixed in ext.js 2.0 ?
This is why pages are loading slowly.
I'm using ext.js 1.1.1 full.-->

Even after following all the suggestions above, Extjs grid is extremely slow. Under Chrome and IE its wicked fast. I have no problems loading 600 rows with 5 columns under Chrome or IE. What is strange is when I go to scroll up or down with the slider or pressing up/down arrows the CPU is pegged. But if I scroll with the middle mouse wheel there is no delay. Moving Column headers around there is delay.
