+Problem position
+================
+
+I have `chromium` and `firefox-esr` installed. I want `gvfs-open`
+to default to the latter when opening a web URL.
+
+Alternatives
+============
+
+There are /etc/alternatives entries for `x-www-browser` and
+`gnome-www-browser` that can be manually edited using
+
+    # update-alternatives --config gnome-www-browser
+    # update-alternatives --config x-www-browser
+
+Unsuprisingly, this won't have the desired effect. Life
+would be too simple...
+
+GNOME MIME
+==========
+
+The default browser for GNOME applications is determined using
+`gvfs-mime`. Per-user overrides can be specified in
+`~/.local/share/applications/mimeapps.list`. System-wide
+defaults are generated by `update-desktop-database` and
+stored in `/usr/share/applications/mimeinfo.cache`.
+
+Quoting https://wiki.debian.org/MIME:
+
+> The mimeinfo.cache is basically a raw reverse cache for the
+> .desktop information. There is no way to define priorities in it.
+> To be able to specify default applications, a mimeapps.list file
+> (previously named defaults.list up to debian 5) must be created.
+> It can be system-wide (in /usr/share/applications or a subdirectory)
+> or user-specific (in $HOME/.local/share/applications).
+
+And indeed the fix was to reorder the list from `mimeinfo.cache`,
+and create the following file:
+
+```plain /usr/share/applications/mimeapps.list
+[Default Applications]
+x-scheme-handler/http=firefox-esr.desktop;chromium.desktop;google-chrome.desktop;
+x-scheme-handler/https=firefox-esr.desktop;chromium.desktop;google-chrome.desktop;
+```
