this question has been asked multiple times like 1 and 2, but their solutions won't work anymore. Probably because of Plasma 5 and the new firefox versions.
So I am using Kubuntu 15.04, Firefox 40.0 and KDE Plasma Desktop. My default file manager is dolphin. Except Firefox opens another file manager - probably some gnome file manager, because it has no info menu to see its name. But ps -ef suggests, it is nautilus.
What I tried so far
- In
/usr/share/applications/mimeinfo.cache, change toinode/directory=kde4-dolphin.desktop;(..) - In
/usr/share/applications/defaults.list, change toinode/directory=kde4/dolphin.desktop(why use a slash here? See this answer). - installing package
kmozillahelper- but this is no longer available. - checking xdg-open by verifying that
xdg-open $PWDopens dolphin. This works, but not for firefox. - removing
rm ~/.mozilla/firefox/<profile>/mimeTypes.rdfdid not work either, as suggested here. Verified, that there is probably no user setting overriding dolphin with nautilus:
[~] $ grep -R nautilus .local/share/mime [~] $
So, I'm sorry to re-ask this question, but things have changed. How do I let firefox open folders (download locations) in dolphin?
