The addon doesn't seem to work in Firefox 123 (the tab counter widget is simply missing). Please investigate.

Installed 1.4.0, quit then started Waterfox.

Hovering does not work until after a click.

In (at least) the first window, the count of loaded tabs is wrong – zero. Mozilla bug 1378459, maybe?

Back to 1.2.0, sorry.
