CentOS

Under 64 bit CentOS 7 with latest updates, Firefox 52.6.0 ESL "print to file" has been unable to print to a .ps or .pdf file--doesn't even generate an empty file; SeaMonkey 2.49.1 does not have this problem. about:config reveals nothing about Firefox or SeaMonkey that I can see that might account for these observations. Nothing about this at mozilla.org, and the print debugging hints there don't solve the problem. Searching the web turned up nothing relevant in the first hundred or so non-hits. Anybody know what to do?

Probably selinux is blocking this. Try:

That took care of it--thanks!
