The extension is fine, however it doesn't work on vertical tabs (it doesn't appear in the menu if I click directly on the tab). It would also be good to offer a link to GitHub (if hosted on GitHub) for added confidence in the developer.

A must have. Used the old version as well. Thanks l_shadowflare_l :)

I need reload for all tabs excluding the active tab.

I use this 1 billion times a day.

It does a great job of assisting page loading and helps in refreshing the page so it's loads all the way.
