I'm getting a PR_CONNECT_RESET_ERROR on my PC when trying to web browse. Same problem with other browsers. Was working fine till a few days ago The URL box has 'Not Secure' before each URL address I try. Have looked up solutions on YT to no avail eg clearing cache etc

My Laptop has no problem with this.

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to nrega.nic.in because this website requires a secure connection.

What can you do about it?

nrega.nic.in 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.

Probably nothing, since it’s likely there’s a problem with the site itself.

Clear Error code: PR_END_OF_FILE_ERROR This is only on Amazon.com. Secure Connection Failed

An error occurred during a connection to www.amazon.com. PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

Hi All, I want to block traffic on firefox externally for managed devices via Intune, following the import of the ADMX/ADML files into intune.

I have set '\Mozilla\Firefox\Exceptions to blocked websites' to the following

• //*.mydomain.com/*

which works, however, I also want to add hosts that are only resolving on IPs and not DNS. I can add specific IPs if known, but is there a way I can allow IP ranges? Ie

• //10.10.*/* (this doesn't currently work)

Of the included screenshot, only the wildcard for mydomain.com and the specific IP currently work

If there is a better way to do this via intune for firefox only, please let me know.

Thanks

I'm using firefox in my company's intranet, it needn't to check whether the website is secure or not. So this warning is so annoying.

I want to turn it off, but how? The instructions I searched on the Internet are out of date.

The browser version is 137.0

Firefox is giving me an error on https://stemgateway.nasa.gov but the site is perfectly accessible using MS Edge and using Firefox on another computer. I uninstalled and reinstalled Firefox, changed the proxy settings to not use a proxy, tested a VPN, and changed DNS servers. Below is a picture of the error and of the certificate which seems to be present in Firefox already.

Subject: Urgent Assistance Needed with Certificate Installation

Dear Team,

I hope this message finds you well. I am in urgent need of assistance regarding a Linux-based system where we have the Firefox browser installed. I need to establish a secure connection with one of my servers, which requires the installation of a certificate.

However, I am unable to locate the certificate export button in the certificate view or anywhere else in the browser. I have tried several methods without success.

Could you please help me with this issue as soon as possible? Your guidance would be greatly appreciated.

Thank you very much!

Best regards, Kishor

I have an website which I prior to this error message have visited many times on Firefox and had no problems. Recently though around two days ago I noticed that I couldn't get in and was met with the following message "Warning: Potential Security Risk Ahead". I can't bypass it apparently and I really need to be able to access this site as it's a University site.

I can access the site on other browsers such as Chrome and Edge but I use Firefox as my default browser and I'd like to keep it that way. I'd appreciate any help I can get.

Why are you closing the baked-in cert expiration support thread two days before it happens? Wouldn't it make a whole ton more sense to leave it open during the actual problem period?

I am able to open all these sites in Edge and Chrome. Firefox is not allowing me to open any website including https://support.mozilla.org/1/firefox/141.0.3/WINNT/en-US/firefox-help

I have never ever had a problem getting into my bank account until this evening.

Says it is insecure.

How can this happen? I really need to get into my account!

When trying to access many popular websites with Firefox on my Fedora 43 installation, I am greeted with a security warning page with the SEC_ERROR_UNKNOWN_ISSUER error. For most of these websites I can simply accept and continue, but HSTS-only sites will not permit this.

Affected websites include but are not limited to (based on exceptions in the certificates section of Firefox settings):

• github.io (many subdomains)
• purdue.edu (many subdomains)
• iu.edu
• ebay.com
• cbsnews.com
• iwm.org.uk
• home.cern
• celestrak.org

Any help in resolving this is appreciated.

When I try to log into a site I have used dozens and dozens of times in the past, I get the following notice: WARNING: POTENTIAL SECURITY RISK AHEAD. This is a dead end from which I have not een able to proceed. The particular site I am attempting to access is the only site where I've encountered this warning. I called that site and was told that while they have been tweaking their security, since the warning message came from Firefox, I should contact Mozilla for help. So here I am.

I use desktop Firefox with newly installed Windows 11 (my profile erroneously sates w10). i must use the blocked website frequently, and so I need to restore access to it ASAP. It is a high security healthcare site, and as I said, they claim they could not identify a security problem, that the key to restoring my access is through my browser, Firefox.

Can you help me restore my access to the site? Thanks .... KH
