Like materials from "Sandbox" Add to favorites?

Question

Habr

Sometimes, looking through the materials published in the Sandbox, I find something useful for myself.
And I would like to add the topic to Favorites, so that later I could return to it at the right time, but, at least for me, there is no such possibility (maybe due to lack of karma?).
Friends, how can I add a topic from the Sandbox to Favorites? Or is there no such possibility?
If not, then I would like to turn to the Habra Administration with a request to implement something similar.
Thank you!

Answer 1

By means of habr - only by giving an invite. I did that a couple of times. Otherwise, the same mentioned peeep makes a copy of the page for itself, then it is already a favorite bookmark manager. Or File->Save As.

You can also try with a firebug. It worked for me with the inner voice, but not yet with the sandbox. Who can - do it, I'll give the link code :)
