Samsung browser add ons?

I finally was able to install the Samsung browser on my Verizon s7 edge but am not too familiar with it. I found an ad blocker in the play store but was wondering if there was an add on store for the browser or any other suggested add ons? Also More specifically I was also wondering if anyone knew of a way to open new tabs in the background instead of taking me to them when I hit open in a new tab.
