Puntuado con 5 de 5 estrellas

I'm not sure what this add on is supposed to do..?

I installed it expecting it to be like Content Scrollbar, but I get no tabs/headings at all.

Esta valoración es de una versión anterior del complemento (0.3.1-signed.1-signed). 

thank you for review

Maybe it`s a bug, maybe it`s not. You can go to add-on prefs to customize more like "content scrollbar" behavior (in new version 0.4).If it wont help you, please, give me more information about your problem.
