It is so annoying to see that the multiple tabs you had opened may be saved but it just wont open them.

I can't find any way to tell it to save the tabs in a window. It's possible that it will save all the tabs when I close the window, but I'm not willing to close a window just to test that out, lest I lose all my tabs.

Can't load saved pages

It is not ok to closes all my saved tabs immediately without ask me

This extension does exactly what it says: it saves your windows. Too bad though that *loading* your saved sessions doesn't work. Also, it closes all your tabs immediately without a warning.
