Comment 1 for bug 305531

The easiest way to reproduce this bug is to have a X server accepting remote connections then start firefox from another computer using DISPLAY=<ip>:0

Firefox is usually fast (as if it was local) but when you right-click it takes 2-3 seconds before the drop-down menu appears. This has also been confirmed with liferea, so it's likely xul-related.

It makes the user experience a lot worse than it was with Hardy's firefox/xul where it was local-like performances for drop-down menus and contextual menus.

This has been tested on the exact same network and same computers on both Hardy and Intrepid, so the network performances, cpu usage or video drivers are not at fault (tried with intel, via and ati hardware).
