In Xubuntu both Chrome and Firefox are default browsers

  • 772

I have a problem in that both Chrome and Firefox says, in their respective preferences menus, that they are the default browser. In Xubuntu's Preferred Applications, Chrome is chosen and 

~$ sudo update-alternatives --config x-www-browser
[sudo] password for xxxx: 
There are 2 choices for the alternative x-www-browser (providing /usr/bin/x-www-browser).

  Selection    Path                           Priority   Status
------------------------------------------------------------
* 0            /usr/bin/google-chrome-stable   200       auto mode
  1            /usr/bin/firefox                40        manual mode
  2            /usr/bin/google-chrome-stable   200       manual mode

the same for gnome-www-browser. So it would seem that Chrome should be the default browser? But the problem is, when I click a link in a Geary mail, Firefox opens. So somehow Firefox is also a preferred browser?!

I've tested the following in the Terminal:

x-www-browser: Opens Chrome

xdg-open http://localhost:8000 : Open link in Chrome

This is fine, but if I click a web link in either Geary or uses "Open link" on the link above, in the Terminal, the links open in Firefox.

Think it may have something to do with the "mimeapps.list":

msix:~/.config$ grep firefox mimeapps.list
text/html=exo-web-browser.desktop;mousepad.desktop;firefox.desktop;
x-scheme-handler/ftp=firefox.desktop;
x-scheme-handler/chrome=firefox.desktop;
application/x-extension-htm=firefox.desktop;
application/x-extension-html=firefox.desktop;
application/x-extension-shtml=firefox.desktop;
application/xhtml+xml=firefox.desktop;
application/x-extension-xhtml=firefox.desktop;
application/x-extension-xht=firefox.desktop;
x-scheme-handler/http=firefox.desktop
x-scheme-handler/https=firefox.desktop
x-scheme-handler/ftp=firefox.desktop
x-scheme-handler/chrome=firefox.desktop
application/x-extension-htm=firefox.desktop
application/x-extension-html=firefox.desktop
application/x-extension-shtml=firefox.desktop
application/xhtml+xml=firefox.desktop
application/x-extension-xhtml=firefox.desktop
application/x-extension-xht=firefox.desktop
msix:~/.config$ grep chrome mimeapps.list
x-scheme-handler/chrome=firefox.desktop;
x-scheme-handler/chrome=firefox.desktop

Don't know what controls this list.

I want only Chrome to be default and also open web links in other applications. What could be wrong?

  1. Here's what worked for me.

    sudo update-alternatives --config x-www-browser

    There are 2 choices for the alternative x-www-browser (providing /usr/bin/x-www-browser).

      Selection    Path                           Priority   Status
------------------------------------------------------------
* 0            /usr/bin/google-chrome-stable   200       auto mode
  1            /usr/bin/firefox                40        manual mode
  2            /usr/bin/google-chrome-stable   200       manual mode

    xdg-settings set default-web-browser google-chrome.desktop

    Verified with xdg-settings get default-web-browser

    output:

    google-chrome.desktop

    I believe you are missing some chrome entries from your mimeapps.list as well. My output after the commands above is as follows:

    grep chrome ~/.config/mimeapps.list

    application/x-mswinurl=google-chrome.desktop;
text/html=google-chrome.desktop
x-scheme-handler/http=google-chrome.desktop
x-scheme-handler/https=google-chrome.desktop
x-scheme-handler/about=google-chrome.desktop
x-scheme-handler/unknown=google-chrome.desktop

  2. Substituting "firefox" with "google-chrome" everywhere in ~/.config/mimeapps.list solved my problem. Links now open in Chrome, and Firefox no longer consider itself as default browser.

    Believe there is a bug somewhere in how "mimeapps.list" is controlled by Chrome/Firefox.
