I will say, though, that there are many examples across various Linucies (that's the plural, right? ☺) suggesting to use the BROWSER variable to change the default browser. Case in point: https://wiki.archlinux.org/index.php/Environment_Variables#Default_programs
And I might add another point: it's obvious that chromium-browser uses `xdg-settings` but I'm not sure what firefox uses, but the end result is that the `xdg-settings`, `xdg-mime` and `$BROWSER` values are all set appropriately. I will note, too, that `xdg-settings` results in a proportional change to `xdg-mime`. I do think that setting BROWSER is problematic and it is contributing to the problem, but the fact that chromium-browser seems to be unique among other browsers in terms of lacking robustness to set itself as default regardless of circumstances. Therefore, I think the fault lies with it. ** Changed in: chromium-browser (Ubuntu) Status: Confirmed => Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1823917 Title: Can't set Chromium as the default browser when BROWSER variable is defined To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1823917/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
