I have installed the browser integration extensions for both firefox and chrome, but whenever I open either program, I get a message to make sure the package is installed. I checked updates-testing and koji, but there is no mention of plasma-5.12.90 or kf5-18.04. I tried finding a copr repo, but turn up nothing. Since the demise of kde-redhat, I seem to be out of the loop for getting the testing updates, even though I have updates-testing enabled.
