When there are multiple windows open, it might be better for us to switch between them for easy navigation, instead of using the task bar.
So, the easy solution is to use the ALT + Tab key combination to navigate between the recently opened windows easily.
Just press ALT + Tab in the keyboard and a small splash screen will pop up , you can hold the ALT button and then multiple press the Tab key for navigating between the recently opened pages.
You can release the keys key when you point the desired window.
This trick also holds well in a lot of Linux machines.
For windows vista, use the Win key instead of the ALT key.
