My problem is that many programs call xdg-open to open websites but on my Manjaro system (based on Arch Linux) this is somehow bound to cups :)

When such a call to xdg-open happens, the CPU usage goes up a lot, without anything happens. I restart because the laptop gets hot very quickly.

~ $ xdg-settings get default-web-browser
cups.desktop

When I want to change that, I get the following response:

~ $ xdg-settings set default-web-browser firefox.desktop
xdg-settings: $BROWSER is set and can't be changed with xdg-settings

I can go ahead and change the environment variable for the browser and I'm fixed, BUT only for this one terminal. How could I make this change permanent or add it to autostart?

I'm using: i3 4.12, fish shell

  • I don't use a desktop, so don't have the right setup and cannot say what GUI tool does this for you, but there is a file ~/.local/share/applications/preferred-web-browser.desktop on my system that has Exec=firefox %u in it.

  • thanks meuh. my issues arise from programs calling xdg-open though which then calls the connected '.desktop' file, that is connected with the task (=default-web-browser in this case). The .desktop file that gets called is cups.desktop, which i find a bit weird and i'm considering deleting cups, because i don't print anyway :)

I had this issue since Chromium made itself the default browser each time I installed it.

Using xdg-mime fixed it:

xdg-mime default firefox.desktop x-scheme-handler/https x-scheme-handler/http

On my Arch Linux system, this added two lines to ~/.config/mimeapps.list, associating HTTP and HTTPS with Firefox.

Now I can have both Firefox and Chromium installed with Firefox being the default browser.

    Add text/html as an argument to also handle .html files in the file system.

  • Thanks, this worked for me in Crostini to keep using garcon to open the native browser in ChromeOS but use the chrome binary for running selenium Mar 3 '21 at 21:08

Check the BROWSER variable in /etc/profile and /etc/environment and eventually in your ~/.bashrc. It is probably set to /usr/bin/xdg-open so you should consider to change it to avoid the recursive call.

  • I have no browser variable in any of those files, is this no longer viable for recent vers?

    My experience: I had BROWSER=firefox in ~/.bashrc but an application still opened URLs in chromium. xdg-settings get default-web-browser produced chromium.desktop, but wouldn't let me set it due to $BROWSER existing. I had to open a new terminal, do export BROWSER="", then run xdg-settings set default-web-browser firefox.desktop and then the application opened urls in firefox. I find that weird, as it's acting like $BROWSER supersedes (and thus won't set), but it wasn't occuring like this in practice. Adding note for anyone else running into this.
