Firefox will not load anymore

Firefox will no longer load. Task manager shows it is running, but nothing comes up on screen. All of this seemed to have started when I downloaded Thunderbird, which I have also deleted off the computer. That is the only thing I have downloaded on this computer. I have noticed a white box appears on screen, bottom right corner every time I try to open Firefox. Nothing is in the box. I have deleted and reinstalled the software. Nothing seems to work.

My system is Windows 10

If you hover your mouse over the Firefox button on the Taskbar, does a thumbnail appear showing that a page has loaded? Or nothing on the Taskbar?
