I'd give this 5 stars if it wasn't for the fact the newer versions have switched out the "X" close icon to the ugly tab thing. Otherwise, this is excellent and really should be a stock option in FF.

Doesn't work. Shows up in my add ons,and shows enabled. but does not appear anywhere else. can not add it to tab or window.

Can't imagine life without this addon. Thank you so much. I have used it for years now!

Alternative button colours would help. Button works fine.

Ok.

Please make it more visible, best make it look like an X.

Please make X icon

Button works just as described (Firefox 57.0.1).
It would be nice to have alternate button colors to improve visibility.

Not quite what i am looking for.
Is it possible to code an add-on that closes the tabs from right to left?
1 click > 1st tab on the right side close the tab. 2nd click > 2nd tab on the right close and so on.

Thank you. very helpful, but can you make the icon look like X?

I just love having a Close Tab button at a fixed position in the browser. Thanks for making this :-)

for your great work to keep the toolbar buttons alive!
