Mozilla & Gecko clones "With the release of Firefox 4 Beta 7, Mozilla returned to near the top spot in browser performance rankings. According to tests run by Computerworld, the new browser is about three times faster than the current production version of Firefox in rendering JavaScript, and lags behind only Opera among the top five browser makers."

I hope they split the UI from rendering

What annoys me about Firefox is that the UI becomes unresponsive when a tab or window becomes unresponsive. Plus tabs shouldn't interfere with each other. I have high hopes and believe Mozilla will make Firefox 4 rock. Go Mozilla!

They did some work on that, I think it was based on the work of Firefox Mobile (which already has seperate processes).

The complete de-coupling of the interface and the content is planned for 4.1. I think, this is complicated because of the add-ons.

If I'm the API already changed for Firefox 4 so it allows to changes to be done.

They only have one thread for handling all gui activities, up until recently that even included the plugins. It's like doing cooperative multitasking instead of preemptive multitasking. If one gui-event doesn't return, everything else stops.

In windows they even reorder input events to fake responsiveness.

If they went over to one thread per tab or if they are even going out of process, this will probably not be a problem anymore. You can gain a serious amount of speed optimising the event handling bottleneck though as every gui event passes thru it.
