I have set Chrome as my default browser yet Kontact only opens links in Firefox. Solution is to add BrowserApplication[$e]=!google-chrome to General section of ~/.kde/share/config/kdeglobals [General] ColorScheme=Breeze Name=Breeze font=Noto Sans,10,-1,5,50,0,0,0,0,0 menuFont=Noto Sans,10,-1,5,50,0,0,0,0,0 shadeSortColumn=true smallestReadableFont=Noto Sans,8,-1,5,50,0,0,0,0,0 toolBarFont=Noto Sans,9,-1,5,50,0,0,0,0,0 widgetStyle=breeze Reproducible: Always
in Plasma 5.14 and git master, changing the default browser using System Settings > Applications > Default Applications > Web Browser > In the following application > choose "Firefox" works for me, even when toggling it back and forth between browsers. Seems like this has been fixed. Notably, ~/.kde/share/config/kdeglobals was not updated yet it continued to work, so it seems like the configuration information is stored elsewhere now, not there.
