Hello, I've recently been trying a few different browsers, altering default browser settings via KDE/Plasma settings software. I've finally settled on a browser, but some apps, when they call the browser, open a page such as; file:///home/brad/.cache/kioexec/krun/49841_0/somepageorother rather than http://url.of.website/somepageorother The number in the 'file:///...' call will be different each time. I've ensured that both gnome-browser and x-www-browser point to the correct browser, but cannot for the life of me figure out why some calls are being mishandled. Note: I'm not pointing fingers at KDE/Plasma, it's almost certainly something *I've* screwed up. My online searches have proved fruitless (clearly my search fu isn't up to snuff) and am hopeful that someone far more knowledgeable than I can shed some light. Using Debian testing, with KDE plasma 5.20 Any help greatly appreciated.
