Links opening in firedragon even after setting default browser as vivaldi

I changed my default browser to vivaldi from system settings. But whenever I try to open link(mainly from telegram) it opens in firedragon. Why does this behaviour exist even after changing default browser and How can I completely change my default browser to vivaldi. Here are some things that I checked xdg-settings get default-web-browser vivaldi-stable.desktop xdg-mime query default x-scheme-handler/https firedragon.desktop
