Hi, i made a new Windows 10 installation this week and i've all the time the same problem, my icon in the task bar disappear when i close Firefox (vers. 83.0 64 bits).
My options for the moment are :
Options > Settings > Lauch the CCleaner app window when the computer starts
Options > Run Smart Cleaning, Run Smart Cleaning when i close Firefox
Options > Advanced > Minimize to System Tray
I tried many options to find the problem but i don't know where i can find the solution. I think i use too many modules with Firefox too.
