Unfortunately, the Thunderbird team has made the application unthemeable. It doesn't use a standard GTK or libadwaita API. Therefore, this is likely to not get fixed, but instead of closing it, I'm just going to keep it in a quasi-open state as an "opinion".
** Changed in: thunderbird (Ubuntu) Status: New => Opinion ** Changed in: thunderbird (Ubuntu) Importance: Undecided => Wishlist -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/2038764 Title: Accentuation colour is blue instead of orange Status in thunderbird package in Ubuntu: Opinion Bug description: Since newer thunderbird 115 ( on 22.04 LTS ) many parts of interface use blue as accentuation colour. I expect them to stay orange ( or any other colour ) as set in Ubuntu appearance settings. Mozilla~TB~team already stated that they won't change that as it simplifies compatibility and maintenance. They imply new themes are needed for TB to better integrate in DE. So the « bug » may sum up to : missing Ubuntu~Yaru theme for Thunderbird ?
