Need a script to click all the buttons of the same type

Hello.
I need a script or a command that will click all of the buttons of the same type on one page. Something similar to Facebook like all scripts or something like that.I will attach the picture of the page and buttons in the attachment so you can have some feel of what I need. On the page, there can be 25, 50 or 100 of those buttons. So, for my needs, that script would save me much time and effort.
Feel free to ask if you have qustions regarding anything.
