- Page closing: I usually get this when pressing Back after opening an external link on Facebook. Looks like an IE's flaw.
- Blank page: Most likely because of weak connection. I sometimes got this problem. Other than that I don't know.
- Crashing: Sometimes happens to me but I'm not sure why.
=> Perhaps you should try another browser, like UC Browser, its quite good.
- Decode error: I think its connection problem since I hardly get this with a strong Wi-Fi, but if with weak connection, oh yeah.. However, when I use a YouTube app, this problem doesn't appear.
=> If you're using YouTube try some of it's clients, MyTube, MetroTube, etc... That's all I know.
