we had a working application with an embedded java applet in an iframe that was performing telnet connections. using a menu selector we were able to switch telnet connections without consequence using firefox until today with the Update to version 3.6.14. That update allows 2 switches to be made but hangs the 3rd switch. There appears to be bug in the new version that is out of our control. We also tried modifying the config file for the browser.link.open_newwindow setting that was set for 2 but that had no effect. This is now affecting our deployment of our web application using Mozilla as the browser of choice.
