I'm on the Sony Vaio, using Mozilla Firefox but I keep getting this error on the majority of websites.

Where is this coming from and how can I fix it?

Any help would be gratefully received.

I also have Bit Defender (in case this has anything to do with it).

When using a corporate proxy via a .pac, why do I get an SEC_ERROR_UNKNOWN_ISSUER for every site outside the VPN?

Switching from Safari to Firefox, I wanted to use the same proxy settings. My first try was to use the system's settings, as it gets automatic proxy configuration from the right URL. This worked alright for Safari! On Firefox however, if I'm connected to the VPN I can access all websites in our VPN, but none outside, as I get the SEC_ERROR_UNKNOWN_ISSUER (can't always add an exception) As soon as I exit the VPN, firefox is "unable to find the proxy server".

I've tried all other kinds of ways to connect via that proxy - manually connecting, by URL in firefox or by automatically detecting, but nothing solves my problem. The automatic configuration shouldn't be the problem as it works fine for Safari and shouldn't be any different for Firefox.

I'd really appreciate any help on the subject.

I got a little gungho when I was trying to figure out why my website wouldn't load on firefox and loaded on chrome and safari - and I did some 'cleaning up' and deleted certificates. Now nothing will load. I've deleted the cert8.db, and tried the steps under "Corrupted certificate store" in this article: What does "Your connection is not secure" mean? Reset Firefox, deleted and reinstalled firefox, and still nothing works, and I continue to get this error on all https sites:

Your connection is not secure

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

Hello,

Just yesterday I started having issues on my computer with Firefox. I play Elite Dangerous and went to the forums to check a recent update, and instead it sends me to an error screen with the message: "SSL_ERROR_RX_UNKNOWN_ALERT."

Screenshots:

I refreshed firefox, deleted cache data/cookiees, etc. I also uninstalled AdBlockerPlus thinking that was the problem. None of these solved the issue, and Firefox works fine on my home internet (same internet as this PC) on my Windows Surface Pro 3 tablet.

Thank You

Microsoft just updated and now Firefox will not let me open up any web sites, except yours. It will not even let me open my Star One Credit Union account saying it is unsecured. I clicked the box that said exception and now it allows me to open this. However, there are still many sites it will not let me access without declaring an exception. I like the fact that Firefox will notify me of unsecured sites, but since it seems to think every site is improperly set up, how do I know which sites are ok and which are not?

The error: SEC_ERROR_UNKNOWN_ISSUER.

This is a recent change, I believe starting with Firefox 55.

Thanks for any help with this!

I can't bypass certificate warnings anymore (HSTS)

In short, I want to be able to bypass certificate warnings.

Yes, I've seen this: https://support.mozilla.org/en-US/questions/1169632 "When there is HSTS(HTTPS Strict Transport Security) set on the server, you cannot add a exception"

In less short, my case (because one needs to always justify one's methods), I set up a subdomain on a separate IP/host and I'm trying to test some project for which I use a webpage as a small visible part. However, the domain uses HSTS (HSTS == very nice).

However, I'm just casually testing something using a subdomain (or even a fake domain, or a real domain pointing to a new server being prepared, maybe using /etc/hosts) pointing to an external or internal IP on some old computer on my LAN or even on my own computer. And that's not possible anymore.

People should always have the option to bypass a warning, and I'm all for the warnings. If anything, there shouldn't have been a box with the option "always remember" ticked by default. There are other cases where this can be useful, some we don't even know yet.

Hi,

I own the following website: http://antarkia.training

It is a private site of my business where we use an e-Learning platform named Moodle.

For years, I've used Firefox to acces it, including today in the morning.

But some hours later, I can't acces it, because Firefox "thinks" it is using a secure connection (https), and it is not "well configured".

When I check the error information, I find this (I'm translating from Spanish):

antarkia.training uses an unvalid security certificate. The certificate is only valid for the following names: training.uwpd.wisc.edu, www.training.uwpd.wisc.edu Code error: SSL_ERROR_BAD_CERT_DOMAIN

The domain https://training.uwpd.wisc.edu/ also uses a Moodle platform, that I checked some days ago.

If I add the exception to Firefox, instead of seeing the "antarkia.training" Moodle webpage, I see the "training.uwpd.wisc.edu" Moodle webpage.

I've cleared the cache, cookies, etc., as well as all the exceptions I've created in Firefox, through the advanced options of the configuration (preferences) area.

Any suggestions will be appreciated.

PS If I usea another browser (Google Chrome, Opera, SeaMonkey), everything works well).
