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.
