This looks happen when the system color support is active. Could you try a workaround?: TST Options => For developers => Color scheme => Photon

I'm also affected by this issue.
Workaround worked for me just fine.

Workaround worked for me too.

The commit f09654b2445ca484620f38e366ef60fab6bd9471 should fix this unstable coloring problem. After the commit, system's dark color mode is ignored, and you may need to choose the "Plain Dark" theme manually.

Here is the (re-defined) policy about color scheme of TST:

• The system color mode of TST is enabled by default only on Linux. Firefox's default theme on Linux uses system colors, so we also need to use system colors on addon. On this environment, CSS media query based "dark mode" is not supported.
• System color mode is disabled on Windows and macOS. Firefox's default theme on these environments are designed with Photon color scheme, and colors are switched to dark colors when the dark color mode is activated on the OS side. So, TST also does same thing - applies light colors by default, and applies dark colors on the dark color mode.

TST 3.4.6 is now available via addons.mozilla.org, so I close this.
