Has anyone figured out how to make Firefox 45.4.0 on CentOS 6 use xdgurl to handle xdg:// URLs?

Google is full of suggestions that don't work. When I select a an xdg:// link I don't get a dialog asking me what to do like Google says I will. Instead I get a message that says Firefox doesn't have a clue how to handle this URL. Do you want to try again?

I tried about:config

I added:

network.protocol-handler.external.xdg user set string /usr/bin/zdgurl

I don't think those types of prefs are used any more ?

A lot of the information out there on adding protocol handlers to Firefox on Linux is out of date or wrong ...

A couple of ways that work for me (on CentOS 6, using Gnome) with Firefox 45:

1. Create the file $HOME/.local/share/applications/xdg containing

[Desktop Entry] Name=xdg Type=Application Exec=/usr/bin/xdgurl %U Terminal=false MimeType=x-scheme-handler/xdg; NoDisplay=true

Then run:

desktop-file-install $HOME/.local/share/applications/xdgdesktop \ --rebuild-mime-info-cache --dir=$HOME/.local/share/applications

Start firefox and browse to a xdg:// URL - it still prompts for the application use the first time - but after that, it should work OK

Note: I haven't actually done this for an 'xdg' protocol handler - but it works for launching other apps using other custom protocol handlers

2. Set up a protocol handler in a central autoconfig 'mozilla.cfg' file

using Javascript - this is the method I use to automatically add a protocol handler for all users (and doesn't require any user intervention) - let me if you want more details about this method

Hey James,

Thanks for the detailed response. Just a minor error. The file name must have a .desktop extension like this:

1. Create the file $HOME/.local/share/applications/xdg.desktop containing:

[Desktop Entry] Name=xdg Type=Application Exec=/usr/bin/xdgurl %U Terminal=false MimeType=x-scheme-handler/xdg; NoDisplay=true

Then run:

desktop-file-install $HOME/.local/share/applications/xdg.desktop \ --rebuild-mime-info-cache --dir=$HOME/.local/share/applications

I restarted Firefox then I went to visit:

https://www.gnome-look.org/p/1157815/

I clicked on the [Install] button.

I got the dialog box where I chose the handler /usr/bin/xdgurl

I did not get the install dialog.

In a shell:

[mlapier@peach ~]$ which xdgurl /usr/bin/xdgurl

[mlapier@peach ~]$ xdgurl "xdg://install?url=https%3A%2F%2Fdl.opendesktop.org%2Fapi%2Ffiles%2Fdownload%2Fid%2F1476439340%2Frmfixed.bdf&type=fonts&filename=rmfixed.bdf" Traceback (most recent call last): File "/usr/bin/xdgurl", line 21, in <module> if sys.version_info.major >= 3: AttributeError: 'tuple' object has no attribute 'major' [mlapier@peach ~]$

No joy,
