Hello, I have a new computer with windows 11 and set up thunderbird. I use Firefox as browser and tested some settings, dark and light modes. I finally set up 4 different accounts with different domain names, I tried some settings to have the same display with on my other computer with Windows 10. I played with some setting and now can"t bring back light mode. I,m more of a computer user not a wiz. same this happened on the Firefoz browser with boxes around each bookmarks toolbar ans tabs. Any suggestions? Thnak you,
