What OS? Works for me. see screenshot If Windows, what security software are you running? Did you try Firefox in Safe Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode#search

Thanks for the suggestions. I tried clearing the Cached Web Content but not the Cookies and Site Data, and it made no difference. The Post's site came up and then immediately disappeared.

I am using a Mac which is running the latest version of the OS Monterey and I'm also using the latest version of Firefox.

Any other suggestions?

Firefox in Safe Mode?

I have rebooted my computer. And after clearing the cache, I have tried to clear the Washington Post from my history. Neither of these things helped.

I don't understand the comment about using Firefox in Safe Mode. How do you do that for just one site? Firefox works fine on every other site except for the one under discussion.

Firefox in Safe Mode

https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode

Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes), any userChrome.css/userContent.css files, and some other advanced features to help you assess whether these are causing the problem. If the problem goes away, that tells us one thing. If it does not, that tells us something else.
