Tab Group Coloring not working on Windows 10

[industriflow]

Tab group coloring isn't working on Windows 10 in Firefox ESR 52.8. Everything else works. Tab group indenting is working.

Under Windows 7 Tab group coloring is fine with this version of Firefox and the same Add-ons.

I installed TK2 v. 0.12.17, TK2 Tab Highlighter, Classic Theme Restorer (w/ same recommended settings) and other Add-ons I've used for years without any problem under Firefox ESR on Windows 7.

I don't have win10 to develop and test
Can you try PaleMoon on win 10?

Hmm, I'm unable to reproduce this behavior in Windows 10 (x64 Version 1607 LTSB on one PC, x64 Version 1709 on another) with Firefox ESR 52.8.1.

I set up a clean profile, installed and configured Classic Theme Restorer 1.7.6 and TK2 v 0.12.17 and tab group coloring worked. In CTR, I set "tabs not on top (v1) - [tabsontop=false] attribute" and unchecked "Use Firefox titlebar instead of OS titlebar". This doesn't match the recommended settings in the readme 100%, I think they were written for an older version of CTR.

@PikachuEXE Can you update the readme on addons.mozilla.org to reflect the current names of the settings in CTR? The settings page in CTR defaults to the "Firefox button" page, so that's the one I changed first.
