How to set the Default Browser from the Command Line?

Question

Tried to set the default browser using the GUI tools but this didn't work overall. Is there a way to configure the system wide default browser from command line?

Answer 1

Execute the following command in terminal,to change the default browser.

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

Sample output:

karthick@Ubuntu-desktop:~$ sudo update-alternatives --config x-www-browser 
There are 3 choices for the alternative x-www-browser (providing /usr/bin/x-www-browser).

  Selection    Path                    Priority   Status
------------------------------------------------------------
  0            /usr/bin/google-chrome   200       auto mode
* 1            /usr/bin/firefox         40        manual mode
  2            /usr/bin/google-chrome   200       manual mode
  3            /usr/bin/opera           90        manual mode

• Press enter to keep the default[*].

• Right now I have firefox as my default web browser.

• If i want google-chrome as default browser then I will type 3 and hit enter.

Note:

• If you want to configure a commandline browser,then you have to configure

  sudo update-alternatives --config www-browser

• Alternate way is to add the following line export BROWSER=/usr/bin/firefox to your ~/.bashrc

• Add the above line in the last,

  

Alternative GUI Method:

• You can also set the default browser in Gnome applications,type the following in terminal and press Enter gnome-default-applications-properties
• It will Open a Window.Now you can choose your preferred browser to set it default.

Answer 2

It depends a bit on what "default browser" exactly means, i.e. for what purpose you want to change the browser. Some programs ignore any system-wide settings and use their own settings.

That said, you can set the default browser for all programs starting the browser with the generic sensible-browser command by exporting the BROWSER variable, e.g. add a line to the file ~/.bashrc:

export BROWSER=/usr/bin/firefox

The other generic way of calling a browser is x-www-browser, this one is handled by the Debian "alternatives" system:

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

If you want to configure a commandline-only browser like lynx, you have to configure www-browser instead.

Answer 3

The already suggested methods might not work for some app (e.g. HipChat).

I've had to do:

xdg-settings set default-web-browser chromium-browser.desktop

Answer 4

Try the following commands:

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

Answer 5

Additional to those answer google-chrome has usually a symbolic link to the channel-specific version:

/usr/bin/google-chrome -> /etc/alternatives/google-chrome -> /usr/bin/google-chrome-beta

Answer 6
