After upgrading to 78.7.0 I cannot open Thunderbird because "platform 78.6.1 is not compatible with 78.7.0". Previously Thunderbird was running. What can I have to do? Tks

Hello there We have read your message. We try to help you.

try to Start Thunderbird in safe mode. http://kb.mozillazine.org/Safe_mode That is how you indentify your problem with software for Thunderbird use.

go to the add- onn manager or extensions search and look for an extension named Xul Runner or everything that looks like it. If there is some extension add- on remove it and try to restart thunderbird again

Or reinstall Thunderbird after deleting every profile of the software from Thunderbird. A fresh install.

C:\Program Files\Mozilla Thunderbird\ C:\Program Files (x86)\Mozilla Thunderbird\'

Try to use 64-bits Software? 32-bits is possible oke.


Greetings Firefox volunteer.
