hi, we have seen a couple of reports where external software (like netsupport school) was hooking into firefox causing this. a firefox beta version 76.0b5 was just released and has a potential fix for this - could you try it?: https://www.mozilla.org/firefox/all/#product-desktop-beta

on the first start it will likely exhibit the same problem, but after you force-close it once and restart the beta build, firefox should hopefully be back in working order.

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
  • Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see
