I have Brave set as default browser and when i select some text in Konsole, right click and try “Search-> Search with Google” Brave opens but instead of doing a google search it displays the html of the webpage. This does work fine with Firefox and even Chromium. I also tried deleting my Brave profile but this still happened.
I recently edited the Brave entry via Kde’s menu editor and the resulting desktop file in .local/share/applications for some reason did not have the %U in it but the system wide desktop file from the package manager does have it.
After deleting the local desktop file it started working correctly again.
