I-Firefox Isithangami Sokwesekwa

A couple users at our site intermittently receive a SSL_ERROR_BAD_MAC_ALERT error when navigating to Google in Firefox. This happens in Version 99.0.1 (64-bit) on Windows 10 computers. When the issue occurs, users can navigate to other websites without issues. Navigating to Google in a different browser works no problem. Restarting the browser will resolve the issue. Clearing cookies and site data has no effect. Users can also refresh the page after some time and the issue will go away.

Any idea as to why this is happening?

I recently updated the SSL certificate for my business. My Firefox browser indicates the certificate is "not secure." When I navigate to my website using Bing, the SSL certificate shows as being "secure." I'd like the SSL certificate to indicate it is secure using Firefox browsers. Is there something I can do so that when someone lands on my website using Firefox it will correctly show that it is a "secure" site?

Thank you.

Greetings. I can't open most sites I usually visit (even google.com) via my Firefox 98.0a1. This happens since today. All error codes are SEC_ERROR_LIBRARY_FAILURE.

Tried to:

• Disable DNS-over-HTTPS.
• Disable HTTP/3.
• Disable proxy (never had it enabled anyway).
• Disable sending info to Firefox developers.
• Change settings of DNS-over-HTTPS.
• Restart the browser (after each action).

Nothing helps me... But I still can visit some websites, but most common resources are not working for me. Please help me because I can't use Microsoft Edge without getting mentally ill. :/

from whatever reason can't go to Rockler.com on Firefox - bud can on other browsers?! An error occurred during a connection to www.rockler.com. PR_CONNECT_RESET_ERROR

Hello, I've been unable to access google mail/drive recently, w error code SEC_ERROR_UNKNOWN_ISSUER and certificate issuer CISCO. i don't have any antivirus software, I've tried resetting the proxy, clearing cache, reinstalling Firefox, nothing works. If this continues I'll have to definitely move to another browser - with which I have no problem accessing those sites... Help please? Thanks

Hello,

yes I know that version 3.6.28 is quite outdated now :) What is 20 years comparing to life on earth.. :)

Thing is that I need exactly this version of firefox because only with this version important web project works and now it is impossible to connect to server because I think TLS 1.0 not supported on server any more and old firefox can not handle the new one (do not know for sure, this is my opinion). So now I have very serious problem as I can not use needed web resource and deadline is tomorrow :(

So questions as follows: 1. Is there a way to force to work firefox 3 with web address https://varzybos.bki.lt 2. Maybe I can use non https:// version if all certificates are turned off in some way ?

I tried to add exception, then tried to play with various config option, nothing helped. So at this moment I am desperate.

Thank you so much.

Hi, We currently connect to a vendor devices admin page that is inaccessible via Firefox because of the following error "Secure Connection Failed" (Error code: SEC_ERROR_INADEQUATE_KEY_USAGE) and won't present the option to proceed via the "Advanced" option. Long story.... The vendor is aware of the issue and as the configuration page is always accessed internally and uses TLS in some form they do not want to allow us to make any changes to uploading our own certs.

Anyway recently I was made aware of a keyboard shortcut to force firefox to bypass the error screen and force a connection, however I have not been able to find it since on the Shortcut guide for firefox. Can anyone provide me with this shortcut, It will save having to switch between multiple browsers.

Thanks is Advance,

I need a FireFox feature that allows me to access the typical Cable Modem Gateway Web Manager addresses (192.168.0.1, 192.168.100.1, etc.) even when they have no security certificate.

I have been using a Arris SURFboard SBG6782-AC Wireless Cable Modem Gateway (purchased at TARGET) for over five years without significant issues. About three weeks ago my MoCA network began having issues. I tried to login to the WEB Manager of the Gateway at (192.168.0.1) using FireFox. I got the following FireFox Msg:

Secure Connection Failed

An error occurred during a connection to 192.168.0.1. Peer using unsupported version of security protocol.

Error code: SSL_ERROR_UNSUPPORTED_VERSION

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

This website might not support the TLS 1.2 protocol, which is the minimum version supported by Firefox.

I finally used an old version of "Internet Explorer" which allowed me to bypass the security warning and connect via a direct ethernet port of the gateway. Evidently someone (Spectrum claims they didn't) downloaded a different firmware version into my Gateway. (D30GW-EAGLE-1.5.4.0-GA-10-NOSH) i.e. not the factory original version. The WEB Manager interface is different, password requirements are enhanced, the MoCA feature can't be enabled, and it seems Arris no longer provides a security certificate for the 192.168.0.1 Gateway address.

Considering the complete lack of cooperation of Spectrum and Arris, I think it is unlikely that I will ever be able to recover the factory original firmware; So... How about adding an "exception" feature to FireFox settings to allow me to at least access my "unsecure" Gateway. I really don't want to go back to using IE. By the way, I wrote this on a WIN 8.1 HP laptop. My main machine is a Dell XPS8300 running WIN 10.

Thanks, Robert R. Hurley

I note that there are 399 posts referring to this problem. The problem has existed on my PC for about 4-5 months.. DELL support has checked my computer, we have cleared cache and browser and tweaked other controls but nothing helps. I have no problem using Google Chrome. If so may people are having the same problem surely Firefox should be making an effort to fix the bug??!! Just drafted a reply to you from Firefox site but as frequently happens message appeared -

 Something about oops and an error message. When it occurs drafts do not save and messages do not transmit.

Sorry the screen print will not copy across.

I use Firefox as my main browser and it is inconvenient to have to swap between Firefox and Chrome

Can Firefox please fix this problem?

thank you mlmg

I am on Linux Mint, Firefox 100.0 and I am trying to access a website, https://www.citapreviadnie.es:38188 (requires personal DNIe certificate). However, I keep getting SSL_ERROR_UNKNOWN_CA_ALERT. If I view the certificate of the website,

1. Firefox doesn't tell me which part of the chain is invalid or not trusted (or I don't see it) 2. When I try to download and import each of the CA certificates, I get an alert saying "This certificate is already installed as a certificate authority." 3. If I try to import the whole chain, I get another alert telling me "This is not a certificate authority certificate, so it can’t be imported into the certificate authority list." 4. If I try to add a permanent exception to the site, I see "This site attempts to identify itself with invalid information", but if I click "view certificate" I'm back to step 1, and adding the exception does not have any effect.

What am I supposed to do now?

Hi,

Firefox is displaying this message: Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to l.mail.people.com because this website requires a secure connection

and does NOT let me continue... HOWEVER, if I copy n paste the URL (https://l.mail.people.com/rts/go2.aspx?h=16465956&tp=i-1NHD-9U-36Hb-1OjSfX9-Hv-5EjIU-1c-Xmrj-1OjOLzQ-l78hyiHVom-1J3ttn&x=6b160f0f640ceeb5fd6f8fe1a3284d4886844914%7c739139%7c20220211%7c021122%7c739139%7c79459191515) to a DIFFERENT browser, there are NO issues with it.

Why is Firefox complaining and how do I tell it to STOP?

I have been trying to get on the Malwarebytes website, but I keep getting;

Your connection is not secure

The owner of links.malwarebytes.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

links.malwarebytes.com uses an invalid security certificate. The certificate is only valid for the following names: *.fortinet.com, fortinet.com Error code: SSL_ERROR_BAD_CERT_DOMAIN

This happens with all of my web browsers. Is it safe to allow Fortinet ?

SSL_ERROR_ACCESS_DENIED_ALERT I keep getting this on different sites, I can't access lots of pages and it's getting to be a massive problem and I reallly need some help. PLEASE can someone help.

Site page that I have used for years is not loading. Keep getting this error message.

Secure Connection Failed An error occurred during a connection to www.hamdata.com. PR_CONNECT_RESET_ERROR

The site is www.hamdata.com How do I fix this?

Thanks Jim [removed email from public]

Have been trying to fix this problem - FF works beautifully if Kaspersky Internet Security is OFF but cannot access any websites when it is ON - just this PR_CONNECT_RESET_ERROR page.

Kaspersky support has been assisting but no solutions as yet. Any help from Mozilla is appreciated. This has been going on for 4 days now.

Using FF version 94.0.2 (64-bit) on Windows 10.

I've tried debugging the extension, errors in attachment

Secure Connection Failed

An error occurred during a connection to 61.5.135.10:89. Peer using unsupported version of security protocol.

This website might not support the TLS 1.2 protocol, which is the minimum version supported by Firefox.

When I add certificate exceptions, such as for my router's self-signed certificate, Firefox forgets the exception at seemingly random intervals. Often this happens in several days. In one case it was overnight. This has been going since at least early 2023, probably a year.

In noticed Firefox also forgets settings like "allow popups" set on a site (like on Gmail for example), but not necessarily at the same time as certificate exceptions are forgotten. Other settings don't seem to be changed or forgotten.

These problems occur on different Macs using the same Mozilla account. Refreshing Firefox has made no difference.

I am repeatedly getting the SECURE CONNECTION FAILED error only for Google-related sites like Youtube, Gmail and Google search. I've to then close Firefox and immediately open it again to see those sites again.

This is the Error: Secure Connection Failed An error occurred during a connection to www.google.com. SSL peer was not expecting a handshake message it received. Error code: SSL_ERROR_HANDSHAKE_UNEXPECTED_ALERT

&

"Secure Connection Failed An error occurred during a connection to www.youtube.com. PR_CONNECT_ABORTED_ERROR"

FYKI, the problem started occurring in November, 2021. It had never happened before. I repeat, this error is occuring only for Google-related sites, not for others.

What could be the problem? Please help!

when trying to access my website Noblittoilandgas.com I get a SECURE CONNECTION FAILED notice, Error Code: SEC_ERROR_REVOKED_CERTIFICATE, how do I fix this issue?
