When loading specific websites, I get pixellated snow on screen. What could cause this?

I have a Macbook Pro, and when I try to load a specific site, dancing pixels appear as it begins to load and disappear after a few seconds.

This started while I was downloading images from an iPhone via Airdrop, and continues specifically when I load one website on Firefox.

I would appreciate any advice to remedy this.

If there is still a problem, Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Did this help?

While you are in safe mode;

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.
