I’d been happy and still, using Thunderbird 60.*. It’s a great desktop application, nothing MOBILE FIRST, to make easier to handle multiple accounts. F-Google’s stop working, saying about protecting my personal information from using the old applications. It’s BS. OK, I had two options
- to use my personal email and get rid off gmail.com (same happened with yahoo some years ago)
- to update Thunderbird… I did it, something around 90.*
… and there is no option to stop this f-pop-up windows, that I need the upgrade. Very frustrated…
You can create your own .reg file
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Thunderbird] "DisableAppUpdate"=dword:00000001
Lazy to create a file? Not a problem, just download a file and update the Registry
