I have given a look at that bug and made a fix - the bug is in GTK+3 (or maybe it's done on purpose, I hope not.)
The documentation on gtk_file_chooser_set_local_only() still says "On some systems non-native files may still be available using the native filesystem via a userspace filesystem (FUSE)." But the code stopped doing that. The patch I sent to upstream (https://bugzilla.gnome.org/show_bug.cgi?id=787128) fixes it. ** Bug watch added: GNOME Bug Tracker #787128 https://bugzilla.gnome.org/show_bug.cgi?id=787128 ** Also affects: gtk via https://bugzilla.gnome.org/show_bug.cgi?id=787128 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/1579543 Title: Firefox 46 is missing network shares in file selector Status in Mozilla Firefox: In Progress Status in GTK+: Unknown Status in chromium-browser package in Ubuntu: Confirmed Status in firefox package in Ubuntu: Confirmed Bug description: Expected behavior: Firefox file selection windows show network shares mounted via Nautilus (i.e. gvfs SMB mounts).
