From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Thank you for replying, very informative. I think I have most of the actions/types I wanted associated with my preferred ones now. The most noticeable one is Firefox when I open downloads from the menu. I'm not sure if Firefox uses xdg or not? I don't mind GTK or Gnome at all, in fact I probably have spent more time on Gnome, but I do like when things are consistent.
Ah yeah, Firefox is GTK too, and annoyingly hides xdg behind a setting. I apologize in advance as my knowledge here is bit limited, but if firefox is installed with RPM, I think you'll need
xdg-desktop-portal-kde
installed, then in firefox's about:config setwidget.use-xdg-desktop-portal
= true. I'm not sure how it works with flatpak though.But hopefully that helps, best of luck!
That's a great tip! It turns out I must have already tried some of that. I found multiple settings in about:config. Anything with a file picker works (open, save as), but the "open folder" from the Downloads dialog must just not use xdg-open, since none of the settings had an effect on that. It's not the end of the world, but it would be nice to have my Dolphin bookmarks and places.
Edit: Adding this here in case someone in the future finds this searching for the problem. It looks like I'm bitten by the bug described in comment 55 (near the bottom) of this Firefox bug report. TL;DR: it works if I have Dolphin open already, but if not, it starts Nautilus. While this isn't great, at least I have a workaround.
Can I just say: hats off to the bug archaeology you've done there :)
