Wondering why regardless of the page I click on, it is never done loading and after what appears to me like all of the content has loaded, I always wind up clicking on the "X" symbol to stop whatever it is doing. (Note using Firefox browser.)

 

I usually restart my iPad when it does that. Sometimes mine won't copy and paste after several days of use and it needs to be refreshed. I'm not saying it'll help you but it's what I do.
