I run the current version of Firefox (152.01) under Windows 11 Pro on a Dell Inspiron 15-3530 laptop. More and more frequently, I'm getting "Access Denied" messages when I click on a site link t56o an internal page. This happens on several sites, most notably Dell.com. I get the error in Troubleshooting Mode, and clearing the cache doesn't help. I've searched the information here, but all the responses seem to involve Windows 7 or Windows 8, not Windows 11. Can someone tell me how to resolve this situation in Windows 11?

Thank you.

when accessing websites where Cloudfare is part of the sequence the page hangs on cloudfare and the page is not displayed. Every time data is transferred through cloudfare the page hangs on cloudfare rending the search useless.

Firefox just updated, now getting ACCESS DENIED at common sites, Home Depot, JC Penney, American Airlines, United Airlines and I don't know how many more.

How do I fix this or go back to previous versions of Firefox?

Or just move to Google?

My mothers new phone won't load external links and mine does?

I have way more strict security settings and same extensions. She has 2 and I have 13 extensions but they overlap and are not the issue. When someone sends her a link her Firefox does not convert the link like mine does, she gets a link in format https://share.google/ + string of letters, when she opens it, it's a blank page. When I open the same link it converts it from that to a regular link (https://). I have installed Firefox to at least 3 other people and none have this issue. I don't have this issue on desktop either.

If it makes a difference: Out all the people that have this browser on their phone she's the only one that has a new phone with Android 16 (mine is Android 14). They are both up to date on both software and Firefox updates.

I've been getting access denied from more and more websites. I messaged a manager from the website shown below, who said my browser was not up to date. I update my Firefox browser when it asks. I did it yesterday, but still got this message today. I haven't updated my macOS because I have been keeping some old software alive. That is no longer necessary. I am now running macOS Mojave version 10.14.6. I can upgrade to macOS Monterey version 12. Is it worth making this update? Will this solve my access denied issue from certain websites? Is there another way to fix this problem?"

I have a 100% repro rate of Firefox redirecting linkedin.com to linkedin.cn. Unfortunately there's another problem beyond the unwanted redirection: linkedin.cn no longer exits, it has been dead for years, I literally cannot reach LinkedIn at all. It was working fine a week or two ago. How do I prevent Firefox from redirecting behind my back? I see the status message (is that what it's called) in the lower left corner "Performing TLS handshake to www.linkedin.cn" and of course it only times out. I just verified with "Web" (different browser), it connects just fine, which suggests that it's a Firefox issue, not a system wide one.

I'm unable to pay for services as it seems the popup from my bank notifying me to expect a text message with a validation code isn't appearing. I've unchecked "Block pop-ups and third-party redirects" restarted Firefox but still the same. This happens with multiple websites. I've also disabled some but not all of my extensions. Only recently started. Changed browser (MS edge) works fine.

Hello! I am a user from Russia. Our Roskomnadzor blocks Firefox sync addresses. Unfortunately, this makes it difficult to synchronize browsers on different devices. Can you tell me how to get around this and keep the synchronization option?

I have setup my Firefox browser to start on a number of pages, using the settings provided in the browser. Recently Google / Youtube started complaining, that my browsing is suspicious

"This page appears when Google automatically detects requests coming from your computer network which appear to be in violation of the Terms of Service. The block will expire shortly after those requests stop."

Which came instead of this url URL: https://www.youtube.com/watch?v=e-zj5cedG-A

I worked around it, by copying the url and pasting it in the browser again But today, it returns the error no matter how many times I manually paste the url in the browser.

I have effectively been blocked from all my startup Youtube pages

I am a business owner and I need to log into united health care provider portal. Mozilla will not allow me to access. I'm using this link: https://secure.uhcprovider.com/ and Mozilla will not allow me to go further. This is causing work stoppage. Chat GPT says the link is secure. HELP! I need access so I can get paid.

From Chat GTP:

https://secure.uhcprovider.com/ I checked that exact URL, and here’s the key point:

👉 secure.uhcprovider.com is actually configured with HTTPS and a valid SSL certificate—so under normal conditions, your browser should show it as secure.

So if your browser is blocking it or labeling it “not secure,” the problem is almost certainly local (your device/network) rather than a new issue with UHC.
