I-Firefox Community Forum

Firefox will not allow me to sign into Facebook. It will not use this address: https://www.facebook.com/ it only uses this one: https://www.facebook.com/ I have cleared the cache in all Facebook sites in my hisotry.

Firefox recently updated on my Windows 11 desktop. As of yesterday (4/24/2026) and possibly earlier after typing www.facebook.com in the URL input space and hitting enter, no results at all.

How do I stop this from happening; never had this much of a problem before.

Access Denied You don't have permission to access "http://www.overstock.com/O-Days-Extra-20-Sale,/link,/results.html?" on this server.

Firefox now blocks my email account... https://my.netzero.net/start/login.do I can log in through Microsoft Edge, however Firefox no longer allows this.

I am unable to load my Facebook . have Googled the problem but am anable to perform most of their advice. I am running W11 and have emptied the cache but this didn't fix the problem. Please help !!

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.

After update, I am denied access to my Xfinity email account: You don't have permission to access "http://login.xfinity.com/login" on this server.

I got to PIA's website, i navigate to the download vpn section and from there, firefox blocks the connection and says the server is offline, Ive just done this chrome and edge with no issue, my issue is that its not only this site itll do this on.

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?

firefox is blocking the following: ctrk.klclick.com I want to allow this. How do i do that? firefox says: website not found. This always happens for Dr. Hyman links to his product. I wanted to unsubscribe and then resubscribe to see if i can fix this problem. but I can't even unsubscribe using his links.
