Can't get share button

I only used it to share to facebook which did not work at all. All it did was present a screen with the URL of the page I wanted to share to copy and paste into facebook. I could more efficiently have copied the URL from the the URL bar. Dumb waste of time. I wonder why anyone would bother with this? I still cannot find how to share from ff to fb from the page I'm on.

This addon adds unwanted spam links. For example, when I post a link to Youtube on Facebook, I get in the title a promotional link to their site. Remove it.

Utterly useless. Clicking on it in the menu does literally nothing.

Added reddit to my of sites to share to, and every time I try to use it I just got redirectd to the addtoanywhere.com website.
