Sir/Madam I am running the latest version of SL6 (2.6.32-279.14.1.el6.x86_64) on AuthenticAMD (AMD A6-3500 APU with Radeon(tm) HD Graphics) I have firefox 10.0.11 Firefox works but it fails to see any printers I did a web search and I found http://ruionwriting.net/2010/11/no-printers-on-thunderbirdfirefox-under-linux-x64/ Now initially I did not have gtk2-2.18.9-10.el6.i686 installed I installed it with a yum command yum install gtk2-2.18.9-10.el6.i686 no error were reported I then rebooted my machine So I added into /usr/lib64/firefox/run-mozilla.sh the line export GTK_PATH=/usr/lib/gtk-2.0/ I then tried firefox but still no printers So I found http://forums.mozillazine.org/viewtopic.php?f=38&t=2600441 But this doesn't work either I have tried downloading seamonkey and opera but same problem There must be a solution But I am stuck about how to find it.
