Hi, delete all references to the website in question, as shown under the heading 'How do I remove a single website from my history?' in this article - Delete browsing, search and download history on Firefox.

Also see Websites don't load - troubleshoot and fix error messages.

If your question is resolved by this or another answer, please take a minute to let us know. Thank you.

Thank you for the suggestions.

I tried the above, and it does not solve the problem.

Good suggestion. I had checked that earlier. Does not affect the problem, which I'm not having in Chrome.

What security software do you have?

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

• https://support.mozilla.org/kb/Safe+Mode
• https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

• Hold down the Shift key and left-click the Reload button
• Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
• Press "Command + Shift + R" (Mac)

Boot the computer in Windows Safe mode with network support (press F8 on the boot screen) to see if that has effect.

thank you for the reply and suggestions. have tried: 1) Firefox safe mode 2) clean install of Firefox (though my history, etc restored via sync) 3) forgetting Amazon.com + deleting its cookie(s) 4) am using the default theme 5) have turned off hardware acceleration 6) bypassing cache to reload page

have not tried Windows Safe mode; that's a lot of trouble for a problem with Firefox but not SWIron Chrome browser.

Amazon also occasionally comes up in Firefox, which makes the problem even more vexing.

It could be your antivirus interfering with Firefox; cor-el was asking about your security suite above.

So what suite do you use? Can you try turning off browser protection like anti-banner and anti-scam stuff or "advisors"?

Thank you for the reply.

Anti-viral protection is not the problem. I have tried Firefox in safe mode with the firewalls and anti-malware off and the problem exists.

The one thing that does work is using a VPN (regardless of firewall & anti-malware). That indicates that it is not a Firefox problem, but perhaps an ISP problem.

Definitely - good testing!
