Whenever I load up the front page, from a new instance of Firefox, I have have about 1 second of time before it hangs, I can’t interact in any way with the website; like clicking links, scrolling, etc.
It looks like this for about a minute, then changes to this:
I can then interact with the page again, the black text disappears when the next image rotation occurs, and the site looks normal again.
I have no further problems with the site even if i navigate away an come back; its only with a new instance of Firefox.
