Your connection is not secure. Error code: MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT

I am a Web developer. I have a localhost XAMPP installation which is not accessible through the Internet. I use the self-signed certificate supplied with XAMPP to enable SSL development. Let me repeat myself — I am doing my development on my own localhost with no access over the internet for my development server. This is my own machine, completely and entirely owned by me. Every time Firefox does an update, it finds a new way to tell me that it has complete control over the machine that it allows me to use only on its own terms. It does everything it can to ensure that I have no control over it.

In light of this, several years ago, I completely uninstalled Firefox, only too happy to consign it to the evil waste heap it so richly deserves. Like a complete idiot I decided to reinstall it about six months ago. Since then, I've spent weeks trying to make it work. Just when I get it somehow to work, it begins to completely bomb again. This last iteration, just one in a long series of iterations, I have spent two complete, entire, and utterly wasted DAYS trying to find a resolution to no avail. That's two days, well over 16 hours, of completely wasted time when I could have been earning money. (When is Firefox going to pay me for what that cost? Where and how do I submit my bill?) It still does not work continuing to give a Your connection is not secure. Error code: MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT error and no alternatives for a workaround. It should be noted that, at no point, does Firefox give me the "Add Exception" button that it formerly gave. (I guess they had to remove that workaround because it prevented Firefox from having absolute control over my machine.

During those two, long, unproductive days, I tried every supposed resolution I could find via Google, including numerous changes to about:config. None of them worked.

The machine that my localhost is installed on is a Windos 10 Pro machine running Apache 2.4. I am using Firefox v.63 with the Flash plugin (not used in web development, of course). My anti-malware is Malwarebytes. When Firefox, the greatest malware of all times, decided to take control of my machine and block my web development, I completely turned off Malwarebytes to ensure that it wasn't the primary culprit. (It had never been at the root of the problem in the past. Malwarebytes makes it easy to add exceptions for an IP address such as 127.0.0.1, the IP universally used by localhosts. In any case, turning off Malwarebytes, of course, did nothing with regard to the issue created by Firefox. Naturally, Firefox would never implement such a simple resolution because, after all, they have to have complete control over my machine.)

My question is: Is there any way to permanently, totally, completely, and irrevocably prevent Firefox from blockading me from doing web development, allowing me to access with ease, localhost web sites, created in the Apache virtual host (httpd-vhost.conf) configuration file on IP 127.0.0.1 and established in the Windows hosts file (/Windows/System32/drivers/etc/hosts)? Or is the only resolution to completely uninstall/trash Firefox from my system and never look back?

Needless to say, I am frustrated beyond belief.

SEC_ERROR_UNKNOWN_ISSUER with self-signed cert

Greetings,

I'm setting a staging server on a VM, and issued a self-signed certificate.

When accessing https://staging.my.site firefox is giving me the following error:

" The owner of staging.my.site has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox may only connect to it securely. As a result, it is not possible to add an exception for this certificate. "

Clicking on Advanced shows:

" staging.my.site uses an invalid security certificate. The certificate is not trusted because it is self-signed. Error code: SEC_ERROR_UNKNOWN_ISSUER "

There is no way to add an exception.

I went into Preferences-Certificates-View Certificates / Servers-Add Exception. Typed "https://staging.my.site", clicked on Get Certificate-Confirm Security Exception. But I got the same message

Restarted FF. Same message. Checked in SecurityPreloadState.txt but cannot see mention of "staging.my.site"

Kindly indicate me how to add an exception for my staging site.

Regards

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.

mailman doesn't allow certificates to be placed on that part of the server, when the server is PLESK. It is an add on feature, and they are not doing it yet. Therefore I'm getting close to self signed certificate error, but with no button available to accept and move go to page... or what ever wording you really have.

I'm trying to get to my own mailman list, that I had no problem creating yesterday. Now I get the certificate warning, but no button to go beyond and take the risk.

I did download and install the new firefox since then, so don't know if that is an issue.

I already searched your site, and tried the options that were available in your trouble shooting areas... but none of them have worked.

Was this caused by the update I did this morning? Anyway, this is my own mail list admin area, and I need to admin my maillist. I can be reached better at we.the.people@peoplesworldwar.com Tammy
