NOTE:
I found almost same addon scrolltabs
I'm cheering this great add-on.
It's solving same problem, using same shortcutkey, and, having same limitation. Interesting. It seems like convergent evolution.
> Limitations
> Due to mozilla's security policy, add-ons not like this one are not loaded in most of the internal pages of the browser, so it will not work there.
> The browser should be in the foreground
> The cursor must be on the page, and the page must have finished loading

I hope this developer will break the limitations.
