I have recently not been able to view important parts of legitimate web site using the Firefox browser.

Could you please submit it via the "Report Broken Site" functionality in the browser menu? I'm looking at the article linked and it's full of errors on their side, but what's mainly missing is some "magic AI" of theirs that only started loading when I scrolled past multiple articles so it's mostly just… slow. They might not be exactly good in optimizing their pages. I've seen a few reports for this site in the recent past where the site rendered broken in unique ways for users usually also over explicit code errors, so this one's not exactly the most reliable. But generally if you're facing similar issues, please do report them. The steps to basically make sure it's not a privacy feature or addon interfering are: # Please check if you have [[Enhanced Tracking Protection in Firefox for desktop|Enhanced Tracking Protection]] (ETP) enabled. You can do that by clicking the shield [[Image:Fx89ShieldIcon]] icon in the left part of the address bar. If ETP is enabled, try disabling it. # If the problem is not fixed, try [[How to clear the Firefox cache|clearing Firefox cache]]. # If it does not help, try [[Clear cookies and site data in Firefox|clearing cookies and data]] for the website you experience troubles with (''warning: you will be logged out on this website''). # If it also does not help, try [[Diagnose Firefox issues using Troubleshoot Mode|running Firefox in Troubleshoot Mode]]. If the problem doesn't persist, please follow the steps from [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems | this article]] to troubleshoot further. # If nothing from the above helps, try [[Manage Firefox profiles|creating a new Firefox profile]] and check if the issue persists there. If it doesn't, you can [[Restore bookmarks, passwords and data from an old Firefox profile|start copying files from your old profile to the new one]] to identify which one causes the issue. See [[About your important data and their files|this article]] on what files to copy. — ''This is an advanced step you can skip if e.g. someone else confirms, or you can see the same in another Firefox instance as well…'' # Finally, if creating a new profile hasn't helped, please check if the issue persists in other browsers (e.g. Chrome, Edge, Opera or Safari). #* If it does, it is most likely an issue on the website's side. You may want to inform the website owner or administrator about that. #* If it doesn't, that's a compatibility issue. Please report it via the browser menu item [[How do I report a broken site in Firefox desktop?]] so that our team there may be able to look into it.
