I’m running a customized install of vanilla Arch, and I’m currently having issues with uploading files with the little “browse files” button. It’s supposed to pop up a window allowing me to see files. (Not the normal full sized applications like Thunar or Nautilus) Are they plugins of some kind to the file browser or something else? Trying to search for them is a bit more of a headache than I anticipated.


If you’re talking about gnome, you might be referring to
xdg-desktop-portal, which should link out of your browser and defer to your DE to complete the requested action by showing a local file chooser.If the browser is asking to launch another default application, it would call
xdg-open, sending an email would bexdg-email, and so on. These are all part of the xdg-utils package, and a list of the tools are here.KDE has it’s own utilsnfor the same purpose.
If yours isn’t firing, you may not have the proper extension utils installed. I would start your browser from the CLI, go to whatever page is expected to launch the file chooser, then see if you catch an error in the output when it doesn’t launch. That should tell you more.
