In the overhauled theme creator on AMO (not Firefox Color btw), there isn’t any way to specify the tab highlight for your theme. This results in weird issues where the tab highlight is in an unwanted colour, which is distracting and irritating. I’m going to use my theme (One Dark Theme) as an example here.
What my theme should look like (Firefox Color demonstration)
As you can see, there is no highlight for the selected tab. This is what I intend for my theme to look like.
What my theme actually ends up as
There’s a white highlight on the selected tab. I don’t want this, it’s distracting. Another minor issue, text inside the tabs have a noticeable shadow effect to them, which isn’t present in FF Color. We should be able to disable this.
Worse still is how my theme appears on it’s AMO listing:
There’s no tab highlight visible. This is misleading for people who just want a dark theme, and end up geting duped.
