I have been having issues with the checkout page of my website. My problem was most likely coming from our payment provider causing issues with updates. I switched payment plugins until it gets fixed. (In case you would like to know the extent of my troubleshooting. I ended up installing a brand new wordpress install on a subdomain and the error still occurred.)

This is most likely not related to my initial payment provider issue. When I view issues in the console I keep getting error messages. These issues affect my ability to use the checkout page on my Firefox. We are currently processing payments successfully. These errors do not show up on Chrome.

Content Security Policy: The page’s settings blocked the loading of a resource at inline (“style-src”). moz-extension:88:56 Content Security Policy: The page’s settings observed the loading of a resource at inline (“style-src”). A CSP report is being sent. moz-extension:88:56 Content Security Policy: The page’s settings blocked the loading of a resource at inline (“script-src”). moz-extension:136:52 Content Security Policy: The page’s settings observed the loading of a resource at inline (“script-src”). A CSP report is being sent. moz-extension:136:52

This is the website page I need help with. https://heartlandforest.org/checkout/

I can't tell if this is happening to everyone or just me. I don't know which resources were blocked or where to fix this. My website and my server do not have a CSP. I have been looking for an answer for over a week before attempting to try asking here. Every issue I have noticed in the past week on my site has been one big red herring after another.

Chosen solution

If code in a moz-extension blocked something, that usually indicates one of your add-ons is filtering the page. This could be any of the popular content blockers, such as Adblock Plus, Blur, Disconnect, DuckDuckGo Privacy Essentials, Ghostery, NoScript, Privacy Badger, uBlock Origin or uMatrix. Can you test in Firefox's Troubleshoot Mode? In that mode, Firefox temporarily deactivates extensions, hardware acceleration, any userChrome.css/userContent.css files, and some other advanced features to help you assess whether these are causing the problem.

If Firefox is running:

You can restart Firefox in Troubleshoot Mode using either:

  • "3-bar" menu button > Help > Troubleshoot Mode... (before Fx88: Restart with Add-ons Disabled)
  • (menu bar) Help menu > Troubleshoot Mode... (before Fx88: Restart with Add-ons Disabled)

and OK the restart. A small dialog should appear. Click the Open button (before Fx88: "Start in Safe Mode" button).

If Firefox is not running:

Hold down the Shift key when starting Firefox. (On Mac, hold down the option/alt key instead of the Shift key.) A small dialog should appear. Click the Open button (before Fx88: "Start in Safe Mode" button).

Note: Don't use the Refresh without first reviewing this article to understand what will be deleted: Refresh Firefox - reset add-ons and settings.

Any improvement?

This looks like a problem with an extension that tries to inject a CSS file on those pages.

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 userChrome.css is causing the problem.

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

I think it's my adblocker ultimate plugin. I have it turned off and it still breaks the page. I think because it still functions for what it expects is a 3rd party scripting. Even though the inline is loading it from my site. I'm going to message them about it. Thanks for the help.
