Better than nothing ) Why, because for Android I don't find better extension that this. Easy and useful, made with good UI, enough of options. But mobile FF made each link not in tab - but in window. And this made for optimization, because windows could go to like sleep mode and tabs by FF logic - not. In this case each link it own window with one tab. But I think if needed, somebody may found another extension to refresh all windows, and than it can be exported by this extension. Anyway a lot of thanks to developer!
