Issues with Windows 10, version 2004

I installed Windows 10, version 2004 and ever since, I've had issues opening Firefox. I have to click on it a couple times to get it to open and then when it does open it's a giant silver square. Eventually it loads, but it takes quite a long time.

Prior to this version of windows, I had zero firefox issues. I'm using FF 77.01 (64-bit)

Hi 415guy,

Try opening firefox in Safe mode,

  • Find the Firefox icon or click Start and type Firefox.
  • Hold down the Shift key on the keyboard and then click the Firefox icon.
  • In the Firefox Safe Mode window, click the Start in Safe Mode option.

If it doesn't worked, then feel free to ask in Reply Section. thanks for raising your question in Mozilla Support Forum.
