Since FF 78.0, we cannot access self-signed certificate sites due to HSTS

The issue described here does not affect version 77.0.1 and earlier, only 78.0 and later.

Update: Wrote an complete analysis on this as HSTS for human beings HSTS for human beings

So, we have a number of internal sites employing a self-signed certificate with a CN not matching the hostname. As an example of such devices are HP iLOs, switches and a series of others that are now completely inaccebile through Firefox.

Up until version 77.0.1, we were getting the usual notofication about the two issues (not trusted and cn is wrong) but we could Add an exception and proceed.

After updating to version 78.0, proceeding is not offered as an option, due to HSTS requirments.

hostname.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.

Troubleshooting done already; Completely deleted everything (FF and profiles and start clean - same issue Renamed SiteSecurityServiceState.txt so FF can create a new one - same issue Imported the certificate into Firefox as an exception manually as per images attached - same issue

At this point, there is no way to access those sites no matter what we have done and the issue persists up to the latest current version of the browser.

Just as a hint, the same issue appeared the same period of time (during the summer) on Chrome and Chromium Edge.

Do version 80 arrived and my passwords departed. So did all my open tabs. I’m more worried about the passwords. I don’t have avast or avg only windows defender. I tried going to a previous restore point but that didn’t work. I tried copying the old Firefox data files across and that didn’t work either.

Could really do with some help here as I have hundreds of logins.

Thanks, TeeKay

I am using Firefox on an old Ubuntu machine, and found myself unable to disable the auto update feature of Firefox. I understand why Firefox wants to do auto update, but for me personally it's negatively impacting my productivity. Many times I was looking up reference materials only to be told that I need to restart Firefox because it just updated itself. Imagine how frustrating it is, especially when I use the Private Browsing mode a lot to avoid having to clean up browsing history and cached files later. All in all, while the auto update feature might be good for some users, it's just not working for me, so I want it to be disabled.

I tried a couple of things. First, there's nothing in the "Preferences" page related to the auto update. Second, I tried to change the value of "app.update.auto" in the "about:config" page to false, and it still does auto update. Finally, I tried to add a "policies.json" file to "/etc/firefox/", with the following content:

{ "policies":

  {
    "AppAutoUpdate": false,
    "DisableAppUpdate": true,
    "DisableTelemetry": true
   }

}

Yet it still does auto updates. As a matter of fact, it updated itself to version 80 just now. This driving me crazy. Any useful suggestions will be sincerely appreciated.

I know, this has been asked before, but either the answer did not help or the addons to solve the problem were removed. In ealier versions the popup for entering the masterpassword did popup when a site asked for a password. Now it pops up some seconds after the start, usually when I'm typing an URL or a search. How to change that? May I either set the seconds somewhere after which it pops up or set FF to not steal the focus if I am typing (which is a very bad behavior!) or change it back to only ask if a site requests a password? I'm frustrated enough to disable the masterpassword which can't be the solution. Thanks in advance

Opening FF today had error message about bookmarks and something (sorry cant remenber exact details) but had to shut down & restart which I did and now, whilst bookmarks are OK all my logins & passwords have gone. Opening the logins.json file shows nothing - it's empty. Checking the about:profiles shows the current one plus 2 others. One has logins but is from 2018 so most are wrong, (most of my currect logins have the firefox generated passwords) the other has none. Can I get them back?

Hello everyone, Trying to find out if my Mac Mini has been infected with flashback. Using this terminal command,

defaults read /Applications/Firefox.app/Contents/Info LSEnvironment,

I got this response:

{MallocNanoZone = 0;}

It should read:

The domain/default pair of (/Applications/Firefox.app/Contents/Info, LSEnvironment) does not exist

I cannot find anything about this and was wondering if it indicates anything malicious. Anyone know about this? Thanks.

Firefox refuses to visit https://discordapp.com, complaining about SEC_ERROR_UNKNOWN_ISSUER. Upon inspection of the certificates, the root CA is "COMODO ECC Certification Authority" - Serial Number 16:E5:86:78:E0:70:94:39:4B:DF:DB:4E:FC:A6:3B:DF.

The Firefox certificate manager contains a trusted entry for "COMODO ECC Certification Authority", however it is a different cert with serial number 1F:47:AF:AA:62:00:70:50:54:4C:01:9E:9B:63:99:2A.

I'm wondering what's the cause of this situation? Did Comodo recently change certificates? Can somebody else check which version of the "COMODO ECC Certification Authority" is shipped with their FF?

For a few days now, whenever I boot up my PC and I click on Firefox to start, instead of starting with the homepage it automatically starts with some sort of ad, usually to update Flash or something. I didn't screencap any of the addresses, but they're definitely random-looking ad addresses. And as far as I know I haven't installed or downloaded anything sketchy to cause this. Any way of remedying this?

I use Bitdefender on a couple of computers. It gives me notifications that Firefox has attempted to contact certain sites that BD lists as dangerous. My question is why Firefox (whether then open or not) would be contacting these sites of its own accord i.e., not because I am initiating any search or other activity. Some of these sites appear to be normal commercial sites, but perhaps a bad certificate or something, like a Carribean airline, CapeAir (I flew a few years ago). Is there something stored in Firefox that would cause it to initiate an outbound attempt to contact these sites? Thank you for any suggestions/information.
