Firefox Community Forum

I am unable to access my usual sites such as @creates or Civil service.Gov.UK or Civil Service Jobs - GOV.UK I am getting this message when I attempt to:

Firefox detected a potential security threat and did not continue to atcreates.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

"civilservicejobs.service.gov.uk has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site. The issue is most likely with the web site, and there is nothing you can do to resolve it."

Advance provides: Someone could be trying to impersonate the site and you should not continue.

Web sites prove their identity via certificates. Firefox does not trust civilservicejobs.service.gov.uk because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates.

Error code: SEC_ERROR_UNKNOWN_ISSUER

These are ligit websites that I need for work. Heeeelp!

Bought a new Macbook Pro with 26.6.2 and need to transfer all bookmarks from old Macbook Pro 10.14.6, I tried exporting the profile from the old Macbook but it did not work.

My home page has always been www.google.com.Today when going there i have no option to search because the search button is gone,and all i see are ai prompts.I click my home page icon,and still get the same thing.

I am currently unable to access certain websites, particularly banking sites. The following error appears: Secure Connection Failed

An error occurred during the connection to modern.ttbank.ir. The peer's certificate has been revoked.

Error code: SEC_ERROR_REVOKED_CERTIFICATE

   The page you are trying to view cannot be displayed because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this issue.

This is happening even though I was able to access this site without any problems until yesterday.

Hello, my laptop is a HP envy, 64 bit operating syste, x64 based processor. I have Windows 11 Home 25H2 version. Right now I have Firefox extended Support release, 115.390ers (64-bit) and my google email says this is not supported, also some of my credit cards websites won't let me use Firefox either. But I have Windows 11 so I don't understand why it keeps saying I have Window 8. I would like to update to the new version of Firefox that is normal for Windows 11 Thank you for your help.

Firefox has stopped displaying the COX home page at https://www.cox.com/residential/home.html?campcode=redir-myc-hom . I can see the back pages if I connect to them from a link, but the home pages does not display. All I get is a error that says, "Oops something is wrong. Please try again later. And a circle that just "buffers" constantly. If I connect though a book mark to the payment page or one of the other pages I can see it. The error used to start for a minute when I turned my computer on and correct itself but now it is permanent.

Cox is telling me that it is a Firefox issue and I should get "another browser". But there is nothing better then Firefox. Everyone else works, even Google and Yahoo, just not COX.

Thanks.

since my last update I am unable to access 4 web sites which I normally use.I have firefox ESR and am on windows 7. Edgesuite is blocking two of my sites, Sephora and Argos and QVC tells me they are unavailable. Scottish Power tells me there is a client error.

Please help.

Starting on Wednesday, 8/19/26, Firefox ceased working on my Windows 11 computer (it still works on the Windows 7 computer). One possible problem is the 1Password extension I added recently. However, it worked for a few days with the extension with no problem. The other suspect is a change to Firefox. On Wednesday morning when I opened Firefox there was a message that I could now stream games directly on Firefox. It has never worked since I got that message. Does anyone have any ideas what I can do to get Firefox up and running again?

I need help with an issue and would like guidance on how to resolve it. I can provide relevant details, including what happened, any error messages, what I’ve already tried, and the steps needed to reproduce the problem.
