This is a report from a reddit user [1].

> Starting yesterday I have been getting a white page with a spinning loading 
> wheel randomly, mostly when a tab is loading and I go to another tab. But more
> and more it's happening when I just switch between already loaded tabs. I have
> the latest version of firefox with the latest updates, windows 8, and yes I did
> that "About:Performance" thing and nothing on it shows that it would cause this
> out of the blue.
> 
> I have noticed this mostly happens with Youtube and Tumblr (I have add-ons for
> both but like I said this just started yesterday and I've had both add-ons for 
> a while with no issues like this)
>
> Sometimes it lasts for less than a minute other times it lasts for at least two
> minutes if not more.
