I just paid my bill with no issues. see screenshot Did you try Firefox in Safe Mode?

Post a screenshot of what you're getting.

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, DuckDuckGo PE, Disconnect, Ghostery, Privacy Badger, uBlock Origin), always make sure such extensions do not block content.

• make sure your extensions and filters are updated to the latest version

You can try these steps in case of issues with webpages:

You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.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

Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Settings), click the padlock icon (Clear cookies and site data) for the domain in the selected tab.

"Remove the Cookies" for websites that cause problems:

• Settings -> Privacy & Security
  Cookies and Site Data: "Manage Data"

"Clear the Cache":

• Settings -> Privacy & Security
  Cookies and Site Data -> Clear Data -> [X] Cached Web Content -> Clear

• https://support.mozilla.org/en-US/kb/clear-cookies-and-site-data-firefox
• https://support.mozilla.org/en-US/kb/how-clear-firefox-cache

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

• switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
• do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window

You can check for issues with Enhanced Tracking Protection. Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.

• click the shield icon for more detail and possibly disable the protection

You can check the Web Console for relevant-looking messages like blocked content.

Thanks for the suggestions. Have tried all. Page appears in Troubleshoot Mode but still can't figure out how to fix. But I can access and change information in Troubleshoot Mode so I guess that will be my go-to when I need to change payment information.

Do you have content blocking extensions?

• https://support.mozilla.org/en-US/kb/use-troubleshooting-information-page-fix-firefox

Only content blocking extension that I have is AdBlock Plus. I unblocked the payment methods page but it still didn't work. Still scratching my head....

I also have ABP. Can you post a full browser screenshot showing the issue? Also check for ETP, the shield icon in the address bar for other 3rd party blocked content, but I have no issues with that.

Page appears in Troubleshoot Mode

Try disabling all your extensions.

I'm having much the same issues with https://www.weather.gov/pqr/barcams which is a US government website. The page loads up fine but tries to connect with datejs.com for content to display. It takes minutes until it finally show up. I've disabled all of my security software and tried it in troubleshoot/safe mode with in change in behavior. I delete and clear cache and history every time I close the browser so no left overs to cause trouble. It does load and show content in MS Edge normally. What is Firefox's issue with datejs.com?

Hey Neil,

How's it going with bill payments.? I just paid my bill with no issue. see screenshot
