Doesn't do anything Puntuado con 1 de 5 estrellas

Installed this add-on. Nothing has changed. Am I doing something wrong here?

works great Puntuado con 5 de 5 estrellas

thank you, dev, for the add-on. why Mozilla thinks we'd prefer to look at annoying title info instead of URLs, I will never understand.

It works! Puntuado con 5 de 5 estrellas

I can't understand why the browser developers will not place the URL in the top bar or at least provide the option through settings or about:config, but this at least this add-on is available. It works as advertised and allows me to have the URL show in the top bar. If I could give it more stars I would.

thanks for the addon works great, the decision to hide the url by default is incredibly dumb.

I apologize for the inconvenience. When I checked the issue, as you pointed out, the download link (a green button) was visible from a smartphone but invisible from a tablet like Nexus7. Unfortunately, I have no idea why the such differences occur. However, a similar issue has already been reported on Bugzilla (Bug733276). Please see the following page. Thank you.
