[regression] borders around tabs in preferences are invisible

Status changed to 'Confirmed' because the bug affects multiple users.

What is the last version that still worked fine?

Setting regression bug to critical status

Is this still an issue with Thunderbird 60.4, the currently supported version?

Hey Paul,

I am sorry but I am no longer able to test that.

Can anyone else jump in?

Thank you! 🙃👋

Yes - still there - but theme dependent. Ambiance and Radiance are the same as in your image.
The Arcs (dark, darker) work, though the borders are hard to see.
High Contrast works.

I tested Thunderbird 60.4 in an Ubuntu 16.04.5 live session with both Ambiance and Radiance and found the tab borders to be very faint but they were there. The border of the selected tab was definitely visible but admittedly not to the extent of when using the Adwaita theme which is what I normally use. Setting back to confirmed for now.

Here is a screenshot of mine - running with Ambiance.
DISTRIB_DESCRIPTION="Ubuntu 18.04.2 LTS"
4.15.0-45-generic #48-Ubuntu SMP Tue Jan 29 16:28:13 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

100% reproducible with Xubuntu 18.04 regardless of theme (over 20 installed). Looking for an upstream report.

Still happening in Bionic with the latest 60.6.1, with the default theme.
