not what it says Puntuado con 1 de 5 estrellas
does not work as advertised. only provides a button to "clear session history" in view/toolbar/customize.
The add-on "Tab History Menu" does a better job of what this add-on purports doing.
Sorry. When I developed this, I made the unwarranted assumption that everyone already knew that right-clicking on the forward and back buttons brings up a menu where you can jump around in the history.
I had hoped that those who didn't know about it could look at the first screenshot and see where the menu is. But clearly it's not enough.
Well, it's a confusing interface, anyway. You might try version 2.0b. Yes, it's a beta. Look at the main add-on page, under Development Channel. This version adds a sidebar (which does have built-in instructions, BTW). Just be aware that you might not get automatic release updates for it until you install a release version.
