Perfection.

Almost perfect for its purpose. I would ask for the ability to change the color of the icon to match the theme.

Simple an effective, it gives me a single place to easily and quickly click for closing the current tab. Plus, it's a pale color and works nicely with my darker shade Firefox theme.

It takes brains to be simple

This close button doesn't follow pinned tab, so the pinned tab will be closed even it's pinned.

Can't imagine life without this addon. Thank you so much. I have used it for years now! I love having a few close buttons for easy access

Works. Put a very light gray cross icon (the icon is different from the addon icon, and no screenshot is provided), the icon sits next to the URL bar, one click and the current tab is closed.
But for visual reasons, I prefer Close tab context menu, that shows a bigger, dark, black icon.

The icon should be customizable, it would be better, or less difficult to see. This addon is for people who has few icons in the bar, or want a very unobtrusive icon.

@Andralon No screenshot is not good for users, but it's never a reason for a one star review!!!!

Tested with Firefox 60.0.2 x86.

Very interesting!

Thanks amokk.

Yeah! Back to user friendly interface!

P.S. And I agree with raveren, about the simple cross icon.

Does the job, however the icon is not the best choice IMO, why not go with a classic X:

So what? It's a simple Close button..., one could say.

Yes, it is, and it does exactly what a normal user would expect to find natively in a browser: a button to close the current tab.

Mozilla seems to "think different" now. Fortunately clever people are not disappeared from the face of the world AND we're still allowed to drag extension icons to the Tab Bar... so far.

GOOD JOB, mr. Amokk!

For some reason the good folks at Mozilla decided I did not need this extension, so it was disabled.

While I would prefer the ability to tell Mozilla where I want my close tabs button(s), this extension does exactly what it says and it does it well.

As for the ability to resize the icons, you could rename them, but it could possibly end up disabling the extension if the Mozilla tactics are similar to those of Microsoft for verifying drivers, etc.

One of the bits and pieces I missed when TMP faded away.

It would be nice to let one chose the icon size, I've seen them inside the XPI.
