Firefox Keeps running at background after closure

more options

After closing firefox, 6 instances of the process keep running consuming 50% of the CPU (snapshot attached).

I haven´t any issues to restart firefox, however I have to kill the processes manually in order to completely close it.

I am using Windows 7.

Right-click on an empty spot in the Windows task bar and select Task Manager (or press Ctrl+Shift+Esc). When the Windows Task Manager opens, select the Processes tab. Select the entry for firefox.exe (press F on the keyboard to find it) and click End Process.

It doesn't solve the problem. It kills the process, however, it happens again after using firefox.

The process should automatically disappear after closing the application.
