FF puldown menues become EXTREMELY slow when computer is connecte to a network
I've got a very strange problem. Firefox (3.6.10 on Suse 11.3 64-bit) runs nicely unless the computer is connected to the network. Working offline everything is pretty perfect but as soon as I pulg in the ethernet cable and the computer is connected to the network, it takes about 5-6 seconds (!) for a pulldown menu to show up after clicking at it. This happens to FF's own menue (File, Edit, View...) as to the bookmark tookbar pulldown menue as well. When I disable the connection, either by unplugging the cable or setup/software, everything is back to normal again. The same happens when I conect via wireless network, so the problem is unrelated to the ethernet interface. I've disable all add-ons but the problem remains the same. Any idea as to what I can do about it?
