PLS how remove this line

[Mopslik]

Hello, i like your old style Firefox, new is bad for me. Please, how remove this line in active tab.

I modify this in user.js:
user_pref("userChrome.icon.panel_full", true); // Original, Proton
user_pref("userChrome.fullscreen.overlap", false);
user_pref("userChrome.fullscreen.show_bookmarkbar", false);
user_pref("userChrome.tab.static_separator", false); // Photon
user_pref("userChrome.decoration.animate", false);

I found this but dont work for me:
userChrome.tab.photon_like_contextline false);

Thanks for help, bye.

Are you using userChrome.tab.connect_to_window to true?
If not, set its to true.

If the problem occurs even if it is true, try updating the theme to the latest version.
If you're still having trouble, it may be a bug in specific OS or theme.
Please tell me the OS, theme with URL, and UI density you are using.

There seems to have been a communication mistake in the theme URL.
For example, I needed information for a theme I install from the add-on store, like this(This is because problems may occur depending on the background image or transparency):
https://addons.mozilla.org/en-US/firefox/addon/google-chrome-dark/

When I have some time to rest, I will try to reproduce it according to your information.

Good job, the problem is in theme, i used this:
https://addons.mozilla.org/sk/firefox/addon/proton-to-photon/

When i change to other, bad line is gone. But i like photon blue.
In this theme is line much thinner.
https://addons.mozilla.org/sk/firefox/addon/photon-colors/

Pictures:
When is true and my old theme: user_pref("userChrome.decoration.animate", true);

When is false and my old theme: user_pref("userChrome.decoration.animate", false);

When is true and my NEW theme: user_pref("userChrome.decoration.animate", true);

But this theme has other problems for me. :)
I dont lie new Firefox design... :/
