This morning I updated Mozilla Thunderbird to the latest version, see attached image. When I open Thunderbird for 20 seconds I only see a full screen white image for at least twenty seconds, then the program starts normally and everything seems ok. In previous versions it never happened 100%. There is definitely a bug in this version. Hopefully we will have an update soon that will make everything okay again. I have been using this software for years without any problems, until now. Thank you. Rossano Zanga, SUI.
