I want to share current opened tab url on facebook wall from chrome extension. For that, I was using https://facebook.com/share.php earlier which was giving me login option
Accepted answer doesn't work for me.
https://www.facebook.com/sharer/sharer.php?u={url}
There is a tool that generates sharing dialog: https://apps.lazza.dk/facebook/ (© Has Facebook sharer.php changed to no longer accept detailed parameters?), here is an reverse engineered example:
https://www.facebook.com/sharer/sharer.php
?u=${url}
&picture=${pictureUrl}
&title=${title}
&caption=${caption}
"e=${quote}
&description=${description}
