Greetings, During normal operations, my firefox icon disappears and I have to do a fresh install to get in back. There's no timetable to how long it will stay. I'm running Kaspersky Endpoint Security 10 and there's nothing blocking the browser. The firefox does not have any extensions installed. I have approximately 60 windows 10 computers in the work environment and only one user is having an issue. The icon is not on the taskbar but when working properly, just sits on the desktop. Thank so much in advance for any help, Brandon
