Yesterday while using Firefox my keyboard quit functioning in Firefox (Windows 11). I closed everything and restarted the computer. Everything else works fine, but Firefox would not load. I tried to the repair function and that wouldn't load. I tried to uninstall and that wouldn't load. I uninstalled with a third part app, and tried to reinstall, but that keeps giving a can't install message after trying for several minutes. I tried to install Firefox Beta and that installer hangs up at [Execute: "C:\Program Files\Mozilla Firefox\default-browser-agent.exe" register-task 308046]. Also cleaned registry.
