And therefore. Recently in Krunker there are some popup ads, you can get rid of them! Open settings, find your configuration, and save it. A window will appear, asking where you want to save the settings, then you should see something strange in the downloaded folder, or a hidden folder or data that you haven't downloaded, if you don't want popup ads, delete it, and remember the folder that was not downloaded, and this is in the folder Downloaded.
I hope to help!
