Firefox 51.0.1(32Bit) on Windows 10 Pro build has this new problem.
Your browser is open and, you have couple of other windows (notepad, Microsoft Edge, Excel, etc) open and all of a sudden the window display is frozen. You click here and there but no reaction. How do you get out of this?
The only way I have found is by invoking the Task Manager. As soon as Task Manager comes up the problem goes away this time around, and you can bring to the top any window you want. It can happen again.
Who is the culprit?
I am not sure if it is the OS () or the Browser. I have seen this happen with Microsoft Edge as well. Probably it is OS build that is the culprit.
