Easy scrape but there is a catch! please help

Hi, I'm trying to scrape this
https://dubaisouth.my.salesforce-sites.com/CompanyDirectory

I tried with pagination for Next, no luck.
i tried with elemtn click for next. no luck.

No matter what I do i cant get the plugin to click the button (firefox and chrome)

I'm trying to scrape the tables one.

no problems at all....
