Is the Firefox useful or hateful?

I did not know what was the firefox used for before I join into it. I found recently it is often interrupting me to surf many websites. It always popup to stop me to watch my opening a website.

I feel very tired in doing so from time to time, really make me feeling hard in front of my computer and desk. I thought whether I can cancel my firefox which is so often disturbing me.

Another question is there a white-cross-red-button always appears to avoid my surfing too.! What is that meant to have this action to appear?
