I have two web browsers installed on my system (arch with i3 wm): qutebrowser and chromium.

I have the following set

Code: Select all

echo $BROWSER #qutebrowser
xdg-settings get default-web-browser #org.qutebrowser.qutebrowser.desktop


As well as the default applications (in mimeapps.list)

Code: Select all

x-scheme-handler/http=org.qutebrowser.qutebrowser.desktop;
x-scheme-handler/https=org.qutebrowser.qutebrowser.desktop;


When clicking on a URL anywhere else in my system (e.g. terminal), qutebrowser is open as expected.
However, okular instead launches chromium when a URL link is clicked. I cannot determine why.

The okular handbook says "the default KDE handler" will be invoked on clicking a link - what might this refer to on my system (if the above is not a bug)?

Any help would be appreciated.

What web browser shows up in the Default Applications module of the KDE system settings?

I do not have the Desktop environment (Plasma) installed so cannot check this setting.

Is it perhaps possible to edit this setting via a configuration file in ~/.config? I can currently only see kdeglobals which has the content

Code: Select all

[$Version]
update_info=filepicker.upd:filepicker-remove-old-previews-entry

[KShortcutsDialog Settings]
Dialog Size=995,618


Hi,

I had (until 5 minutes ago) the same problem: arch with i3, no kdesettings application to immediately change default browser, and okular alone opens hyperlinks in firefox instead of brave.

$ xdg-settings get default-web-browser
brave-browser.desktop

Thanks for the suggestion about kdeglobals. Adding the following to the end of .config/kdeglobals solved this for me:

[General]
BrowserApplication=brave-browser.desktop

Thanks for sharing what worked for you. In fact, since I made the original post (over 2 years ago) it seems some KDE update resolved the issue for me personally, but I've made a note of the BrowserApplication directive if the behaviour returns, and am sure others landing on this page will find it useful - thanks!
