Running Hardy means using Firefox 3 Beta 5 per default. When I first visited the http-server of one of the devices in my customers datacenter, the screen was frozen after a second. Unfortunately the device’s http-server stayed frozen. There was no further connection possible. Even worse: This could be fixed only by cutting the device’s power.
Currently I have no idea how to work around.
Edit:
There is a workaround. Install firefox-2. Set up a new profile foobar:
firefox -profilemanager -no-remote firefox
Start firefox-2 like this:
firefox-2 -P foobar -no-remote &
