To summarize, when using firefox/iceweasel in X2Go, the browser frequently hangs for between 16 and 20 seconds. All other applications work perfectly fine, accept input, and display output, but the browser window remains frozen. Once it unfreezes, all input and output is processed, e.g., typed letters are displayed and tab clicks are executed. It appears to happen in AJAX intensive sites (Zimbra, GMail, GLPI) but this is not definitive.
The smells like Nagle, but who knows.... Can you give information on your connection parameters. For example: I'm in a LAN and noticed that I get the best results using no compression (rgb) - but one in a while there are small errors in the disply (e.g. an immage not being updated correctly) - opposed to png. I also have the gnome-system-monitor-applet running, therefore data is sent continuously. I would also be interested whether the whole screen hangs (e.g. including the system monitor) or only the single Applicaiton. Maby you cold start xkbwatch and see, whether the keystrokes (e.g. shift ) still arrive at the server.
