I wonder if the style isn't compatible with themes with images or cause of my bad apply of the theme.

The selected tab shows a color in the selected tab instead to display the image behind.

What's your theme?

I installed the Lepton version 7, and additionally I used this: https://github.com/black7375/Firefox-UI-Fix/wiki/Show-Off-Your-Config#australis-like-theme but with a theme with images like this: https://addons.mozilla.org/es/firefox/addon/beautiful-gx-fantasy/

I should delete that line?
I just have a leptonChrome.css with all the rules, I should download with code-> download ?.... I'm lost jeje

and the code is to show the line around the tab, maybe that is the problem.

user_pref("userChrome.tab.box_shadow",                false);

You can set the above option to false, but there is no border.

There is a reason for this implementation.

At first, it was implemented as SVG's stroke, but it was very rough. #511

oooh, so the tab-line disappear jeje thanks for your help.

Rather than using rough curved borders across all themes, I decided to trade-off at the expense of compatibility in a transparent background theme.

I understand, make a complete compatibility with a lot of styles is very hard. Great job.
