Chosen solution

You can try to disable hardware acceleration in Firefox.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

I am not sure if the immage uploaded in my previous post. So here is how it looks. Third image also shows a Chrome window opened without the blue squares. They are only in the Mozilla window.
