Trouble with Internet browser

I've been able to watch movies, on 123movies, without any trouble. Aside from the issues the site has had, lately. I hears of 123hulu, as an alternative for streaming movies. When I try to watch a movie, on 123hulu, everything slows down. Even after hitting the home button, it can take more than a minute, or two, to get back to the home screen. After about a minute, things seem to go back to normal.

I've tried deleting stuff, to free up more space. I've downloaded the latest update. Netflix and Amazon Prime don't have any issues. What's the problem with Internet browser?

Thanks :)
