If the problem is with a link inside Amazon, then you should contact their customer service or web site maintenance and report the problem to them. If the link is from something else (search engine, bookmark, someone else, and so on) the link may no longer be active.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

• Do NOT click the Reset button on the Safe Mode start window.
