Facebook Game crashes my browser on iPad

I work for a company that I need to use Google Chrome to access many of our programs. I also play a graphic heavy game called HeroWars on Facebook. When playing this game on iPad, or accessing my work sites, the browser crashes. It does it on Safari as well as Google Chrome. I have been told this is because I am using an App Browser not the full browser.

I am interested in buying an iPad Pro, to not have to lug my laptop around especially for quick trips. However, I don't want to make that investment if the browser capabilities aren't powerful enough.

Is there a way to insure I can get the full browser on an iPad Pro?
