This is irritating. If you want to continue using Firefox, you may be able to remove this problem using the Adblocker Ultimate add-on. If you go to the GCP console, and then click on Adblocker, it will show amenu item "Block Element". If you can select the white patch, it will remove it, and keep it removed. It worked for me.
