first I hope you will understand me because I am from Germany and my English could be better.
I do have installed the Version 3.5.x Comodo firewall + defense and Firefox 3.0.3. The Computer is in the printer room and I do need the settings that Firefox is clearing the private data after ending every time. Firefox needs about 15-30 seconds to end and you can do nothing with the computer.
I read that Comodo 2.4 Version did have a problem with this phenomenon and you must set some extra rules for DLL's. After the new settings, FF was fast again. I cannot find this kind of settings in Comodo firewall 3.5.x. Can somebody help me? Does anybody have the same problem? Did you solve it?
