I have a Dell precision tower 3620 desktop, with Ubuntu 16.04 installed. It has already annoyed me so many times that Ubuntu web browser (webbrowser-app) in 16.04 makes my system hang.
The problem is that whenever I open Ubuntu web browser, the system sometimes hangs, but gets restored back again. However, sometimes it hangs, and nothing works except for the mouse. What left to be done after that is to reboot the system by pressing ALt + Print Scr+R+E+I+S+U+B
Is this is only because Ubuntu Web browser is buggy or because of something else?
