Problems with installation of Thunderbird and Firefox in Windows 10
When i installed Thunderbird and Firefox at my laptop in Windows 10 they don't run and i receive the following messages: "Thunderbird (Firefox) is already running, but is not responding. The old Thunderbird (Firefox) process must be closed to open a new window."
