Should be fixed now :) To find where the buttons are, see the above post.

Huh, on Chrome i can only see it on my own profile. Odd

You can use it on your own profile now. Noticed that it can theoretically work on your own profile. I'll investigate why it isn't working correctly on Chrome soon.

Edit: definitely works now :)
