I'm a programmer. I have my main reliable box is windows 7. I'm committed to moving main linux (mint) and Raspberry. I have my other boxes and sbc's running fine. I installed and have installed linux on a laptop and the Thunderbird running on it. I don't know but suspect that running the last version (115) that supports win 7 and it somehow has quit working. It works fine on the laptop but I'm worried that either the "upgrade sync" has somehow not recognized that it was running on the windows 7 and it bumped / prepped the windows ??? I noticed that it just started saying on the latest version that it requires windows 10. I don't want to give in and update windows. It's trash - windows 10 & 11 are crap and have become to intrusive. Help with Thunderbird on my old windows 7 please  ! ! !
