Wallabaggerini por h3nn3s

This is a drop-in replacement for the Wallabag bookmarklet as a page action. I did this
because after having used Pocket for some time, the URL bar felt like the most natural
placement of the button to me.

The default Wallabagger extension is more powerful than the bookmarklet but I did not
want to use it at the time of writing this because it stored the account password in plain
text in the browser storage.
