Hi, We are running RHEL Server release 6.9 with firefox-52.3.0-3.el6_9.x86_64 RPM. We have a user who notes she cannot view gzipped postscript files from the web the document viewer ( RHEL6 evince). The first view is successful, subsequent views are unsuccessful. We think this is because the first view is downloaded to /tmp/mozilla_userid0/filename.ps.gz. Evince can open and display this file. Subsequent views of the same filename.ps.gz files are downloaded to /tmp/mozilla-userid0/ as fiilename.ps-1.gz, . Evince (the document viewer) does not seem to be able to open files with ps-1.gz file extensions. Please let me know if you need more info. Any help is appreciated.
