For Samsung Galaxy Tablet S2, Android, ONLY; tell me name of Spanish to English Translation AAP for use on all websites and webpages automatically.

My only device: Samsung Galaxy Tablet S2 Model: SM-T810 Browser (s): Firefox (preferred 90%), Dolphin, CM Browser, Internet Browser, BlueMail, Google Chrome (LEAST Preferred) Example Problem: I downloaded Mexico's Univision TV Network APP. Unfortunately for me, it is all in Spanish with Spanish subtitles (CC); English subtitles infrequently. My searches for an English version of Univision APP were unsuccessful. There are several free Spanish to English Translation APPS but they all only seem to translate one word or one phrase at a time. Not interesed. I want one free APP that translates entire online websites/webpages automatically, or with the touch on not more than one button which is located on my tool bar or task bar so that translation begins as soon as I open Univision and doesn't stop translating until I tell it to or not until I close Univision. Now, If all you are going to do to "help" me is have your computer send me a bunch of articles to sort through trying to find a needle in a haystack on my own, don't do anything at all because THAT IS DOING NOTHING AT ALL. Just give me the name of such a free APP if one exists. If there is no such free APP, simply say so and we will both be done. Thanks for you help. NOW I'm going to go kick my dog (poor Smitty).
