I am working with the nightly build versions. Recently I installed FF3 to check compatible problems with this browser.
I did not notice any compatibility problem of an heavy dijit/dojox application that I am writing.
In the other hand the performance in FF3 is in some cases much worse than even in IE7/IE6 (the slower browsers I know, for Dojo Toolkit)

When I click a button in FF3, it takes 2-3 seconds until the button receive the click event, grid and charting are very slow too.
The FF2 and Safari browsers behave very nice from this point of view.

My question is: someone know if this is a FF3 problem or Dojo's ?

I will be very grateful of any response on this subjects
thanks
