Trying to completely disable "this connection is untrusted" dialog

I'm trying to completely disable the "this connection is untrusted" dialog. I've had this issue since 3.5 when the security model was changed. There used to be a plugin that reduced the amount of time it took to get through this dialog, but it stopped working with 4.0.
Issues:
I am a systems administrator that managages 1000's of servers & devices. A large number of these have internal websites, and they can be replaced/change frequently (HP ILO's, temporary dev websites, switches, etc.). the frequency of the turnover and the effort to create and assign a certificate to each of these websites would cause a lot more effort then going through the dialog choices. however, the dialog choices frequently slow my work down on a regular basis. Adding an excemption for each website would not work due to the frequently changing nature of my environment.
So to sum up:
I want to completely and utterly turn off/remove the "this connection is untrusted" dialogs from my Firefox. It will save me (and others I would imagine) time and effort to simply disable this dialog completely. I don't care how obscure it would be to get to work, as long as it's an option and it only has to be done once.

'''I am so tired of firefox telling me "This Connection is Untrusted"!!!!!!!!''' I'm tired of having to add exceptions, I'm tired of the extra tiny lag time of loading while it checks sites, I'm tired of typing the URL I want into the URL window only to look up to see that the lag time has now caused my cursor to stop typing in the URL window and has now started searching in my Google homepage halfway through my typing!!
Firefox, '''GIVE US A CHOICE of whether we want secure browsing on or off''' or I am OFF YOU and onto another browser!!!~~!!~!~!!!~!!! Quit forcing things on us like Facebook does with no options to opt in or out if we so choose.

How do I disable "this connection is untrusted" I visit the same web site mutiple times in a day visit I get this same error, these are trusted sites within my work

How do I disable "this connection is untrusted" I visit the same web site mutiple times in a day and every visit I get this same dam error, these are trusted sites within my work environment. This is getting really old, and I am thinking that I should just uninstall, which is a pity becuase I do like firefox

Okay, before you copy 'n paste canned responses, you should read the post first.
'''The date & time on my computer is correct''' I've already checked this.
'''I don't give a damn why the site is untrusted''', I probably know why in fact (behind corporate proxy server).
As for exporting a known good certificate from another browser, sure good idea, but it doesn't seem to work. I tried exporting from IE, Firefox did the import without complaint, but it still complains. At any rate, I don't care about that. '''I just want to permanent disable it for ALL SITES for ALL TIME'''. Is that too much to ask for?
Judging by the number of posts on this topic, apparently I am not the only one complaining about this.

Disable "this connection is untrusted" page

I would like to completely disable the "this connection is untrusted dialog." I am an administrator and deal with many intranet sites. It is not cost effective to set an exception for each site. Corporate standards require us to use either IE, or Firefox, and I would prefer not to have to use IE.
To be clear: I am not looking for a solution that lessens the amount of overall clicks, like in browser.ssl override behavor in "about:config" nor am I looking for an Add-on (like "remember certificate exception"). I am looking for a way to remove the "this connection is untrusted" dialog completely.

This is a huge problem! I am seeing it discussed everywhere.
Read this: http://social-biz.org/2011/10/16/the-anti-ssl-conspiracy/
The thing is: a SSL connection with an invalid certificate is STILL BETTER than a completely open unprotected HTTP connection. This dialog makes it appear much worse, when in fact it not.
If FireFox encounters a "self-signed" HTTPS server, it should browse to it without delay, exactly as if it was an HTTP server. It should not give this scary warning. It also should NOT appear as a trusted site. It should just work like a normal HTTP site ''which does not have a valid certificate either''.
Please let people know how ridiculous this is.

How to disable "This Connection is Untrusted" warning in firefox using shell or perl script running on Linux Platform

We have QA automation jobs that invoke user interface tests in Firefox running on a virtual Linux host.
My tests perform regression, but I'm held up because of the Firefox This Connection is Untrusted warning.
My current requirement is to ignore this connection untrusted warning, which comes up when accessing an HTTPS website and i want this to be disabled through either a shell or a Perl script.
I can do this manually using the steps below, but this will not work for my current problem since the virtual Linux hosts are created dynamically on submission of automation jobs.
Go to Tools > Options > Advanced "Tab"(?) > Encryption Tab Click the "Validation" button, and uncheck the checkbox for checking validity.
Is there any Perl or shell script that disables this certificate warning?

There might be an add on to accomplish this:

How to disable "This connection is untrusted" ?

I just installed a fresh windows xp on my pc and I'm using the latest FF 26.0,but from the start i cant get to some pages,like in youtube,some pages doesnt come up and i get the "This connection is untrusted" page,in the technical details it says "youtube.com uses an invalid security certificate,the certificate is not trusted because no issuer chain is provided.(Error code:sec_error_unknown_issuer).
also when i open FF add-ons manager tab Extensions,Appearance,Plugins and Services are ok but the Get Add-ons tab is not working,i get the same page as i stated above with the same technical details (instead of youtube.com it's services.addons.mozilla.org) and same error.
I've tried all solutions on the web and on this forum like reset FF, adjust time & date, using the "Skip cert error" add-on, deleting the cert8.db file, and so on - none of them helped me with this problem.
If it helps i use Avast! antivirus and window firewall,no other software on that pc.
I'm pretty clueless about what else i can do,any suggestion that might help?
Thanks!

Finally solved the problem...
when I found out with your help cor-er, that the issuer of the certificate is netscape i figured it has something to do with my internet provider, since im using special provider that blocks "adult" sites and other harmfull sites,i needed to add a certein certificated from my provider's web site,after doing so all problems were gone immidiatly.
Thank you so much for the quick respond and all the help!

Is that content loaded in an iframe?
You can check that via the right-click context menu to see if there is a "This Frame" item. 
If that is the case then try top open the frame in a new tab or otherwise check the Technical Details of the error message.

Why am I getting the message 'this connection is untrusted' when trying to access iCloud through Mozilla Firefox?

I use Mozilla Firefox and have never had difficulty before, but today I got 'this connection is untrusted' when trying to open iCloud. There was no option to override this.
The Technical Details said:
www.icloud.com uses an invalid security certificate.
The certificate is not trusted because no issuer chain was provided.
(Error code: sec_error_unknown_issuer)
Help!

Clear your history/cookies and stuff like that on Firefox and then retry. If that doesn't work try restarting the computer or accessing iCloud via Google Chrome or Safari for the time being. I feel your pain, I love Firefox.

You have asked Firefox to connect securely to www.facebook.com, but we can't confirm that your connection is secure.
Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.
I have tried following Solution:
1. Uninstalling firefox completly including deleting profile + reboot + install
2. Reset the Firefox
3. Clear the caches and evreything.
But could not solve my problem so now I am posting this questions. I am using Latest Firefox with Windows 7.

hello, first please make sure that the date, time & timezone are set correctly on your system. if this doesn't solve the issue (or it is already set properly), a possible solution depends on different factors:
* what is the '''error code''' shown under ''technical details'' on the error page?
in case the error code equals ''sec_error_unknown_issuer'', please attempt to add an exception on the bottom of the error page & inspect the certificate (see the screenshot attached for instructions):
* which '''issuer information''' does the certificate contain?
thank you!

Can't skip "This Connection is Untrusted" error page

The SSL certificate for one of the sites I use expired today a couple hours ago, and the devs of that site still haven't had spare time to update it yet. Suppose it's not a big issue, in most (other) browsers you can just review the problem and click on "continue anyway" link or something like that, when you're sure that the certificate was expected to become invalid. So you can visit the page requested with broken certificate in _single_ click. But not in Firefox.
As I remember - some time ago on the Cert Error page there was "I understand the risks" paragraph with the button "Add exception" below. Looks like it got disabled in Firefox 30 as I don't see it there. Okay, I googled around and found out that in about:config page there's a secret option browser.xul.error_pages.expert_bad_cert which was in disabled state by some reason (I personally haven't ever touched it before). Okay, now I'm able to open the ugly "Add exception" window, but when I add exception - nothing happens. Neither temporary not permanent exception option allowes me to view the site. "This Connection is Untrusted", browser says. Period.
After that I've tried to install "Skip cert error" add-on - with no success. Even if I add the site URL to whitelist in add-on options, which "in theory" should bypass ANY security checks for this exactly domain - then I still end up staring at "This Connection is Untrusted" error which simply can't be bypassed by any means.
The sites I've tried to reach are https://lists.openwrt.org and https://forum.openwrt.org. It's interesting though, the certificate is also expired at https://openwrt.org, but that site can be added to exception list and then firefox opens it. However I see completely NO WAY to make firefox open https://lists.openwrt.org or https://forum.openwrt.org.
I've run out of ideas and came here. Hope somebody knows how to workaround this issue.
PS: I wonder why the hell there's no option to bypass the check by some _simple_ means like in other browsers so that I could reach requested site in seconds rather then searching for settings/addons/workarounds for hours. Thank you firefox for such enourmous care for security, you've made me run Internet Explorer again...
Update 1:
It appears that in this case the certificate was registered for domain openwrt.org, but was also used for forum and lists subdomains. Now it is expired, but the expiration issue can be ignored by exception list only for openwrt.org itself. Other subdomains are actually added to exception list, but it doesn't work for them, so that browser is stuck at "untrusted connection" error which can't be ignored or skipped. What a shame.
Update 2:
I was quiet wrong in Update 1: in fact the SSL certificate for openwrt.org was Level 2 certificate with correcly registered subdomains like forum.openwrt.org and lists.openwrt.org. However when the certificate expired, only openwrt.org exception worked and the site was browseable. All the subdomains could be added to exceptions but regardless of that fact firefox refused to open those sites and was stuck on unskippable "untrusted connection" error page.
For now openwrt.org maintainers have already renewed their certificate so the problem can't be observed on those domains anymore. However I believe that the problem in firefox exceptions handling still exists and should be fixed in future firefox releases.

Hi kozaki, this thread is about an older version of Firefox. Could you start a new question?
For what it's worth, I see the "I understand the risk" section of this page in Firefox 33.0.3: https://forum.anomos.info/ -- but I have not added an exception for the top level site, so maybe that's a partial explanation for the difference.
Also, a new release of Firefox is out today which makes some changes for certificate issues.

Firefox Nightly keeps bugging me with "This Connection is Untrusted" on every single site I visit

So I am trying out the new FireFox Nightly, as it was suggested by a friend to me. Now I am liking it at first, but when I remove all my old FireFox stuff (completely uninstalled as there was alot of useless junk/plugins/data that I wanted gone) I am now getting this "This Connection is Untrusted" message on every single site I visit! It even says that the mozilla site is dangerous. So is there any way to disable these warnings?

Hello Rykuu, also, check the time and date of your system, if the date and time on the computer are wrong then security certificates may not be valid.
which security software do you have (firewall or/and anti-virus)?
thank you

Every time I try to log into ANY website that is secured, I get an error message "This connection is untrusted."

The error message is:
This Connection is Untrusted
You have asked Firefox to connect securely to www.facebook.com, but we can't confirm that your connection is secure.
Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.
What Should I Do?
If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.
www.facebook.com uses an invalid security certificate. The certificate is not trusted because no issuer chain was provided. (Error code: sec_error_unknown_issuer)
If you understand what's going on, you can tell Firefox to start trusting this site's identification. Even if you trust the site, this error could mean that someone is tampering with your connection.
Don't add an exception unless you know there's a good reason why this site doesn't use trusted identification.
Steps I have take so far:
Verified that system clock is correct
Cleared all cache, history, cookies, etc.; didn't help
Started Firefox in Safe Mode; didn't help
Disabled all Firefox extensions; didn't help
uninstalled and reinstalled Firefox using Control Panel; didn't help
Ran Microsoft Safety Scan for malware; nothing was found
Other information:
This problem exists ONLY in my user profile and ONLY in Firefox. All 5 other users can run Firefox with no problem. I can run IE and Chrome with no problem.
Problem exists in ALL secured (https) sites.
I use Avast and Windows Firewall. Had never heard of ESET or BitDefender before searching these forums.
A lot of the sites don't give me the option to Make an Exception. The two that I tried to make exceptions for, still wouldn't open.

Untrusted?? REALLY?? maps.google.com is untrusted!?! Oh, and support.mozilla.org is ALSO untrusted? I'm using Chrome to post this because in the case of support.mozilla.org, there IS no option that allows me onto the site.
Pretty much every site I go to has this problem and Firefox is now all but unusable to me. And I'm on a corporate machine, so it's not like I have a lot of options here. And it's not our corporate network, because only a few of us have this problem.
How do I Firefox to work again, and disable this 'feature'?

This connection is untrusted while opening gmail, facebook

As of this morning i have not been able to open gmail or facebook with firefox.
1. I have not made any OS changes or antivirus changes since yesterday.
2. I always set my cache and history to be cleared when i close firefox.
3. I uninstalled and reinstalled firefox a few times (completely following the instructions on the mozilla page where the hidden roaming firefox directory is to be removed).
4. I reverted back to Firefox 32.0.3 and it did not solve the problem.
5. I ran malwarebytes and Microsoft Forefront Endpoint Protection and there are no viruses or malware detected.
6. I am running Win 7.
7. I can open these sites without a problem on Chrome or IE.
8. Google.com opens fine and i do a search for gmail through google.com and it displays the "connection untrusted message". Details are below:

mail.google.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. (Error code: sec_error_unknown_issuer)

Thanks for your input. My issue got fixed. It seemed to be a proxy issue. Once this variable was set in about:config to the proxy name I was again able to access all the above mentioned sites: ''network.negotiate-auth.trusted-uris''. The value of this variable was '''thenameofmycompany.com'''.
I don't know what happened to change this overnight when i did not update the browser but somehow this was the issue. Also looks like when i downloaded and installed firefox this variable did not get set automatically.

This connection is untrusted with Error code: sec_error_unknown_issuer.

Hello,
When I try to open G-Mail & twitter and some other trusted websites, I got the following warning "This Connection is Untrusted" with Error code: sec_error_unknown_issuer.
For most of the site, I can bypass by clicking « I understand the risk » but this is a bummer but for Gmail and Twitter, there is no other button than "Get me out of here"
When I go through « about:support » and « reinitialise » system, I no longer have the problem, but not only it erases all my personnal set-up but the problem always come back when I restart my system
Date and time are set right.
I have also tried to reinstall completely FIREFOX to no avail
I am using McAfee Total protection 2014 & Firefox 31.0 on Windows 7 64 bits.
I have had this problem for the last 5 days and only Firefox.
Other Browser ( IE8.0) is working fine
I have searched for solutions but they all failed -
Deleting cert8.db did not solve the problem either
How do I solve this Problem?
Thanks and Regards
