Windows 10 installation 64 bit 8 giga ram enough hard disk and processing power. We using Thunderbird 2 years now. After the latest update on windows 10 (10/5/2018) Thunderbird is no longer operating, "no responding" on task manager. We try everything, such as safe mode with networking and safe mode on the software, disable antivirus - firewall, reinstalling from the begging (delete profiles) but thunderbird keep not responding. The only thing working is disabling internet but again this is not a solution. Before the problem occurs and the same day the update we try some modification on the language (display - keyboard) if this have something to do with the software. Kindly give us some advice before proceeding and reset windows.
