with Firefox does not start I mean, that it does not automatically start up when I start the system (what it normally does) and if I then start Firefox, I can see it for several seconds in the process list, but it disappears after some seconds automatically without any error messages out of the process list.
Firefox does not launch at all if BZ is active and Firefox is under its control.
If I empty BZ, I understand this means taking Firefox out of Bufferzone, Firefox works normal.
The BZ firewall I did not touch at all.
thanks for the quick response.
