Previously, when the above happens, I get a yellow pop up message . After the latest update this is no longer available. Please reintroduce this, as I sometimes fail to see the pop up window which allows me to stop it. If I fail to stop it in time, firefox freezes and I have to reboot every time. This time make it a red window, so that the warning is immediately noticeable. '''''''''Note'''''':''' I am still using Windows 7. Thank you Victor nanshir Malaysia
