Version: 91.0.1 Settings--> Privacy and Security -->View Certificates-->Your certificates--> pick target cert to delete-->click ok on confirmation window --> click ok on Certificate manager window.

Restart FF, Settings--> Privacy and Security -->View Certificates-->Your certificates, the deleted cert is on the list again.

The same happens on that under Authorities.

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.

Today is the day I cannot use Firefox anymore. It keeps on blocking webservers in my local network because of a self-signed certificate.

It is a shame, I have been a loyal Firefox user since Netscape. Today marks the beginning of the end of this journey. A pitty.

So, Chrome it is from now on.

Problem with one website. I can't load and I see error: SSL_ERROR_INTERNAL_ERROR_ALERT

Dear Mozilla Community,

I have problems with one website. This website is poczta.wp.pl. Sometimes this can't be loaded. I see this error:

"SSL_ERROR_INTERNAL_ERROR_ALERT".

This is website with https protocol. What is the reason? Other websites works fine. I think that this is not problem with my router or internet provider because I changed both and it is still problem there. I had this problem also on another computer with Windows 10 operating system. I contacted with administrator of this website and they think that all is okay so they suggested me that this can be problem with browser or my computer.

This behavior is very hard to test because this issue is showed very rare. Sometime one time in one week and sometimes two time in one day. I don't know what is going on with this.

Can you help?

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.

I need to download a certificate from a device in my networt called secunet Konnektor

https://www.secunet.com/loesungen/einboxkonnektor

on the manual it's written how to do it.

https://www.secunet.com/loesungen/einboxkonnektor#c1607

I suggest to find a manual somewhere in the first link or in google:

chapter 7.4.3

go to chrome (same with edge)

click on the lock on the left hand side of the link https://XXX.XXX.XXX.XXX:8500/management

somehow click on the button where you can open a small windows called "certificate".

The "General" tab shows informations about the certificate.

Click on the tab "Details" and click on "Copy file".

The certificate-assitent opens and after clicking on next, you choose DER-coded-binary X.509 (.CER)

Save the file somewhere where you can find it.

I can't do this on firefox

On firefox I can find a lock on the left hand side of the link https://XXX.XXX.XXX.XXX:8500/management

when i click on it and then on something else, i can then click on more informations.

a windows opens called "page informations"

under "security" i click on "view certificates" and a new tabs opens called "certificate for konnektor".

but there is no possibilty to download a cer-file. only a pem file and it doesn't really help me.

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.

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.
