Alexander Sack , Thank you for your help.
My problem's cause is the same of ppmt's, I have an oldish version of cairo installed at /usr/local/lib and when I uninstalled that cairo version I can print with Firefox 3. But as I need that old Cairo version to use cairo-dock with glitz, I decided give up Firefox 3 print job ( I'll use Opera to print internet staff). -- Firefox crashes on trying to print https://bugs.launchpad.net/bugs/203019 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
