Search and Click!

[jafuuu]

Hi to all users who are helping persons like me at AutoIt Forums!

Im new here, I'm really sorry if I repeat a post that already exist, but...

I was searching and searching and I can find nothing similar to this:

Can somebody tell me how to order to AutoIT v3 click in a button, not using coordinates, searching the button in a Mozilla Firefox web page and click on it!

I can't use coordinate because, somethimes a text apear and the upper side of the page, somethimes the text are long, sometimes are small, somethimes don't appear, so, coordinates aren't exactly =/!

Here is a screenshot of the webpage, the button is that appear in red:
