Just updated Firefox from version 90.0.2 -> 91.0.1 on a Mac running OS 10.15.7.

I'm experiencing 404 errors of which do not occur in the previous version. Here's what the console shows...

Source map error: Error: request failed with status 404 Resource URL: https://MyWebsite.com/assets/vendor/bootstrap/css/bootstrap.min.css Source Map URL: bootstrap.min.css.map

I tried several things to try and isolate this issue, but all to no avail. The file does exist, and loads in the previous version of Firefox.

Any help would be greatly appreciate.

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!

Can't fix SEC_ERROR_REUSED_ISSUER_AND_SERIAL as described

Hi all,

while playing (or better "fighting"...) with a linux docker container on Win10/WSL2/Ubuntu for using the MS spfx tool chain, I generated a SEC_ERROR_REUSED_ISSUER_AND_SERIAL in FF85.0/Win10 by first setting up a certificate exception for a dev-cert (https://localhost:4321) and then have the certificate re-created.

As described the support article [https://support.mozilla.org/en-US/kb/Certificate-contains-the-same-serial...], I removed all certificate exceptions for localhost:* and deleted the "gulp" authority in options/security/certificates.

Unfortunately, the SEC_ERROR_REUSED_ISSUER_AND_SERIAL persists even after a restart of firefox.

Any help is very much appreciated...

Thanks & greetings Markus Fehn

Firefox Browser Flaw

I am unable to connect to the Nord VPN website or the Express VPN website because of a security issue with the Firefox Browser and I am unable to bypass the security and go to the site anyway. Here is what the message said: Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.nordvpn.com because this website requires a secure connection.

What can you do about it?

www.nordvpn.com 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 website, and there is nothing you can do to resolve it.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

How can I connect to these websites?

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.

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 ?

Firefox giving following error,

Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for 192.168.1.100. The certificate is only valid for the following names: anishamsi.lan:6659, 192.168.1.100:6659, 192.168.1.100, anishamsi.lan

I can see the url is there as listed by firefox error itself (verify with screenshot 1), the url is "https://192.168.1.100/api/validateLogin"

please see the screenshot as well. First screenshot is for the error, second is for the certificate returned by the website and as shown by firefox.

What is the error, i have created the certificate correctly. i am sure this is a bug in firefox?? If not!!! how u suggest i fix this i have added following alt names inside my csr. DNS.1 =anishamsi.lan:6659 DNS.2 =192.168.1.100:6659 DNS.3 =192.168.1.100 I have already uploaded the certificate at names screenshot.

This started happening on many websites this week. Sometimes refreshing the page helps, sometimes it doesn't.

I'm only using Windows Defender and Tinywall (blocks everything through windows firewall) as security.

The websites I'm entering are definitely safe and don't have expired certificates (like Reddit).

After auto update to FF 89.0, access to long-time Fidelity account is intermittently blocked as a security warning, or causes DSL line to drop at submission of account security code, or displays account entry page as plain text, not std HTML formatting, or most often results in a technical error page saying try again later. MS EDGE works fine, no issues. This is the only webpage this occurs on. Fidelity has no FF reported issues on their end nor does my IP supplier. Using desktop PC, running Win10/64-bit, DSL line @ ~ 2.3 Mbps. Using the "Light Theme" which was auto set with 89.0. This plus the new bastardized menus will push me to drop FF since I can't afford endless hours to fix basic functionality with ea update.

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?

Hello,

After upgrading to Firefox 91 when I visit site with self-signed certificate in Private window I always get Warning: Potential Security Risk Ahead error even though the certificate had already been added to exception list while not in private browsing. It looks like in private window certificate exception store is not honored. There was no such an issue before version 91. This behavior is by design or it could be a bug ?
