Since my upgrade to Windows 10 the upper window frame of Firefox ist grey.
"Styilish" did'nt work to adapt its colour to the window frame colour of the windows of other programs (thunderbird), which I chosed in "Coulor" in windows 10 "Systems" by personalizing the computer.

Try the CTR extension.
Look at the setting(s) in the CTR Options/Preferences here:
- CTR Options > Toolbars (3)
With CTR I can alter the colour of the active tab, but I didn't find out, how to alter the colour of the inactive tabs. So the dominating colour of the upper line is still grey. By toolbars (3) it was only possible to chose "Blue Aero", which changed only the adress bar to light blue.
