Feature Request: Menu item to disable Firewall for a period of time e.g. 5min, 1hour

[griccardos]

Often, i need to install something that requires python, node, the store or some other application that has a bunch of sub applications that requires internet access. I certainly dont want to grant them permanent access, nor do i want to allow each and every sub application access for 5 mins, just for an install. I tend to disable firewall, then forget until later to switch it on again.
It would be great to have a menu item in the tray icon where one can disable for 5 minutes, and not have to remember to switch it on again. Maybe useful to have a few different default times e.g. 1minute, 5 minutes, 1 hour, until reboot
