Description Andrew Mike 2018-08-07 21:30:49 UTC
Description of problem:
When opening files from a URL, Firefox will not try to open it in an external application.

Version-Release number of selected component (if applicable):
firefox 60.1.0-6

How reproducible:
Consistently, on a RHEL 6.10 system with a GUI installed per https://access.redhat.com/solutions/5238.

Steps to Reproduce:
1.Open Firefox. 
2. Set pdfjs.disabled = true in about:config.
3. Open a PDF in a URL (like https://www.gutenberg.org/files/11/11-pdf.pdf).

Actual results:
The file is immediately downloaded. When the folder icon in the download pop-up is clicked, instead of Nautilus appearing, the "Launch Application" window is shown.

Expected results:
The file open dialog box should pop up and ask whether to open the PDF in evince or download it. When the folder icon in the download pop-up is clicked, the Nautilus window for the download folder should be displayed.

There's is a fix for this by changing XDG_DATA_DIRS in /usr/bin/firefox to:
export XDG_DATA_DIRS="$MOZ_LIB_DIR/firefox/bundled/share:/usr/share"
