Default How do you stop this **** from refreshing apps by itself?

Let's say I'm on Facebook and in a thread and want to post something relevant to it, I go to Chrome, find the link and copy it. By the time I do that, Facebook has somehow refreshed and I'm no longer in the thread I was in because it refreshes the app as if I opened it again...

Now let's say after scrolling allllll the freaking way down to find the thread I was in, I go back to Chrome... IT DOES THE SAME THING!?

How do you stop this annoying ****? This phone has been nothing but annoying since day one, and I can't say one good thing I like about it, not ONE.
