This looks like bug #369122, except it occurs for any link, in kmail, or even a simple url shortcut on the desktop. This is probably a duplicate of bug #393673, but easier to find since here the error is in english. rm -r ~/.cache does not solve anything, even after a logout. With a new user, it works. So something is wrong in my configuration. But it would be better to diagnose the issue. inspired by https://bugs.kde.org/show_bug.cgi?id=343329#c4: /usr/lib64/libexec/kf5/kioexec cat ftp://ftp.gnu.org/README command= "cat" args= ("cat", "ftp://ftp.gnu.org/README") Copying QUrl("ftp://ftp.gnu.org/README") to QUrl("file:///home/ederag/.cache/kioexec/krun/23201_0/README") <fine README content> So this is perhaps not a kioexec issue ? This does not seem related to firefox either, since /usr/lib64/libexec/kf5/kioexec firefox ftp://ftp.gnu.org/README opens the README in firefox.

In what apps do you experience this? Everything?
Tested in kmail, dolphin, and a link on the desktop. Also happens after selecting some text in okular, and right click>search for ... in duckduckgo.
Another clue: the behavior depends on the link: for links like https://bitbucket.org/me_ydv_5/octave/wiki/Home firefox opens with file:///home/ederag/.cache/kioexec/krun/16436_0/Home in the url bar. For https://bitbucket.org/me_ydv_5/octave/wiki it opens with file:///home/ederag/.cache/kioexec/krun/16471_0/wiki For https://bitbucket.org/me_ydv_5/octave/wiki/ (mind the ending slash), error KIOExec: "A folder named /home/ederag/.cache/kioexec/krun/16497_0/ already exists." System Settings>Default applications>Web Browser>open http and https: changing the existing command: firefox => firefox "%u" solved it. This is definitely not a KIO bug. Closing as resolved, moved to opensuse https://bugzilla.opensuse.org/show_bug.cgi?id=1105623
> firefox "%u" solved it. Not quite: urls are opened twice. firefox opens a new window, with two tabs holding the same urls. Removing the "%u" (i.e. back to the previous buggy state), the urls open normally, just once, in an already existing window. looks like a [2009 thread](https://forum.kde.org/viewtopic.php?t=39446).
Fixed in Frameworks 5.51 with the fix for 397742. *** This bug has been marked as a duplicate of bug 397742 ***
