Highlights and better tab identification

Hello Deleted

I use a low image quality screen, depending on the angle, I can't identify which tab is currently active.
Firefox has an excellent tab highlight and it is possible to know which tab is currently active even on low quality screens.

Notice that there is a white bar at the top of the active tab 

Zooming on the active tab

The white bar appears on light themes.
In dark themes, a blue bar is placed

And it shows which tab is active

This simple bar already helps me to identify the active tab on low quality screens.

There is also another feature
"mouse over inactive tab"

Inactive tab zoom

 See that a bar appears at the top of the inactive tab when you hover over it

The same goes for dark themes

I would like to leave my feedback on these features that may seem simple, but that are very useful.
And I wanted to recommend that there was something like that on microsoft edge.

Dark theme used in the example: Default mozilla firefox theme
