On 1/15/2025 I had to re-install Thunderbird due to an issue I was having. When it re-installed it it completely changed the way it looks and operates. I downloaded the new version from Thunderbird esr channel. Both the Mac and Win10 versions are 128.6.0esr. As you can see they display completely different and when you "tag" an email in the win10 side, it highlights the entire subject line. In the Mac side when you "tag" an email it adds a little tag out to the right of the email subject line. Can I get the Win10 version to display and act the same as the Mac version? At the start of this, they both were 128.6.0esr versions. both displayed the same and, both acted the same.
