Firefox won't open Google without a mistake "this connection is untrusted", and no option to obtain a temporary certificate is available.

This problem arose for the first time a few months ago. but I managed to work around it by clicking on "I understand the risks" on the warning page "this connection is untrusted", then adding a security exception. This fix would work for the lengths of time, sometimes for days, sometimes for minutes. Now, after upgrading to the latest version of Firefox, I get the same caveat of security, but the option to click on "I understand the risks" disappeared. I get this error message on the page of technical details: (error code: sec_error_unknown_issuer)

I have everything listed here repeatedly made: https://support.mozilla.org/en-US/kb/connection-untrusted-error-message
I tell everything. Remove cert.db, start in safe mode, clear the cache, delete and reinstall... Nothing works.

Your help would be greatly appreciated!

In Firefox, you must import into the authorities. The certificate will generally have a .cer extension.

  • Firefox won't open any search with a search engine query. All are UNTRUSTED.

    I run the operating system MS Windows 7 Premium with Kaspersky as my security software.

    Then checked again. It seems to be security settings of Firefox and not Kaspersky causing the problem. Just in case it's Kaspersky, I added Google as an exception, but the problem persists. I also added Google as an exception of certificate in the Firefox config. and the problem still persists.

    The problem:

    I just can't open any page of web search in Firefox through any search engine because Firefox says that all are "unreliable", but I can open these pages in other web browsers.

    Any search gives this:

    Well the miserable loader does not load the image. So much for this, but basically, the notification is that "THIS CONNECTION IS UNTRUSTED" and the issuer of the certificate is unknown. Says error code "unknown sender".

    I do not get the ability to ignore the warning, so I have no other choice but to close the page each time. A nightmare, what makes Firefox unusable. Not sure that this is being caused by a recent Google update or the update of Firefox.

    I've checked then once again my security settings of Firefox and for the life of me, cannot understand why this has suddenly started happening out of the blue.

    Please note:

    1. I have Google as my search engine by default and Firefox as my home page.

    2. I've updated automatically, but had to remove like my Firefox default browser - temporary I hope.

    3. I've never used the default theme of Firefox.

    4. I already re-set/updated the browser by using the refresh/reset link in everything: support/troubleshooting Information. That did not help.

    5. I have Google as a reliable (in exceptional cases) site, in Firefox and Kaspersky, but that doesn't seem to help.

    5. have you spent to help and clicked on everything: firefox and get this report:

    Well there it is again - uploader is still running madly and never deliver - 10 minutes later - nothing downloaded. Version control on my Firefox in a dialog box States: 'FIREFOX 40.0.2 Firefox's update

    6. again on another page the search for my problem, I see this:

    Far out! Why this uploader freaking does not work? I have to type everything, besides being tedious, this gives you no verification. A line of text after another says:

    "Congratulations!" You use the latest version of Firefox.
    "Looks like you are using an older version of Firefox. Update on the Google game'
    "Contgrats!" You use the latest version of Firefox.

    Then further:

    In an area of button: "Refresh Firefox" I made according to the description.

    Immediately below that, it says:

    'Looks like you are using an older version of Firefox'... and in a direct link below:

    "updated to stay fast and safe"... Is this for real? [This would be more credible in a screenshot].

    7 about: support/troubleshooting Information I deleted my profile page and restarted Firefox by following the instructions.

    8. made no difference. Delete the file again and everything closed and restarted the system. That didn't work, either.

    9. all the text that I read in Firefox 'aid' resembles a cached page. I can't reveal all 'real' web pages in Firefox browser in Firefox support at all for some reason any.

    I love Firefox as a browser, but hate its constant glitches. For more than 10 years, I hate to admit it, I used that is never a problem. Then I switched to Google Chrome for another 5 years, with never a problem - outside the mining data and espionage which I hate and that's why I finally changed to Firefox. Firefox is the choice... but it's also a bloody choice as head banging and maybe it's just enough to make me give up on this.

    https connections are there to make sure you're traffic is encrypted and you talk to the Web server that you expect to. What happens technically with kaspersky, it is essentially a man-in-the-middle attack, which firefox reports to you as it should be - your web traffic does not go to google when you type in www.google.com, but for kaspersky.
    There are ways around that for av-vendors (such as the injection of their certificate root in the browser (it might go missing again after an update of firefox), but if there is a problem with you contact kaspersky support because they will be responsible for applying the product they offer properly.)

    in all cases, allowing the characteristics as https in your av software can even let you more vulnerable, because browser vendors have now greater expertise in how to use and implement encryption properly: http://www.scmagazineuk.com/updated-kaspersky-leaves-users-open-to-freak-attack/article/411470/

  • FireFox blocks many sites and said that this connection is Untrusted

    many sites is blocked by firefox like facebook, yahoo mail, and even on this site.
    its saying that this connection is Untrusted
    and this site while working on other browsers
    and I'm sure that the date of the pc is accurate and up-to-date

    What security (firewall, antivirus) software do you have?

    Some monitor of secure connections and send their own certificate instead.

    A few examples:

    • SSL protocol: do not scan SSL protocol
    • BitDefender-> privacy-> settings disable SSL Scan

    Hello, it seems that you run a very outdated version of firefox & old plugins - this is a serious security risk, because there have been dozens of corrected critical vulnerabilities from firefox 3.6 was released (it was more than two years ago).

    You must do the following as soon as possible:

    • Download and install the latest version of firefox from getfirefox.com
    • Check your plugins to https://www.mozilla.org/plugincheck/ & update all those which are obsolete
    • You can also remove all the toolbars you have installed, because they can cause problems. in firefox, go to tools > addons > extensions and uninstall Yahoo! toolbar, motor driven, Radio TV 2.1 Community Toolbar and "Ask Toolbar". then you can launch the searchreset extension to restore the search parameters which leads crushed...
    • do a full scan of your system with your security software

  • Firefox can't open google after update to 13.0.1

    I have this experience after update my browser yesterday. All other sites work well. Only google.co.uk opens. In fact, none of the google services (search, maps, gmail, etc.) doesn't load. It works very well without any problem in Internet Explorer.
    The proxy parameter is fixed (without proxy), but that did not always help.
    Scanning with antivirus did not show anything so.
    Clean history and cookies did not help so to transform all of the installed extensions and plugins.
    Error console is also empty.
    Trying to open google a few times, even without showing any info this page is unavaible or whatever it is.
    The strange thing is that google entering the intellectual property, the site is working properly, it must be the dns problem...

    I tried to empty dns earlier, without success.
    Regarding the twitter page - it loads fine.
    EDIT:
    You said spdy, I went to the config page, and off spdy.
    (network.http.spdy.enabled, false) and now google works as before.
