• Message "this connection is not approved. After choosing 'I understand' Add 'except' and 'confirm dry', need me a modified version of the site.

  Almost all sites Web generates a message "this connection is not approved. After choosing "I understand the risks", "Add exception" and "Confirm Security Exception", it takes me to a lighter version of the site that looks nothing like the real site. Also, I get this message on the sites of Mozilla trying to solve the problem. Under the technical details, it reads, "the certificate is not reliable because no sender string has been provided. (Error code: sec_error_unknown_issuer) "the articles I've read on this subject do not seem to help.

  This happened after I restored it firefox to default settings. I have a copy of my personnel file on my desktop. I tried to put it back in, but nothing changes. I've deleted and reinstalled firefox a few times.

  Any idea would be appreciated. Thank you for your community!

  Unfortunately, certificates of do_not_trust could be a sign of unwanted software on your pc that is to intercept the secure network traffic. go to the system control panel and uninstall programs such as BrowserSafeguard, BrowserSafe, backup or other software that seems suspicious and did not get intentionally installed by you.

• When I type my own field in Firefox I get a message: "this connection is not approved.

  My URL is www.agentandy.com

  Hello Andrew200!
  It can be your current firewall protection (maybe some security software that also offers websecurity). It looks fine for me, do not alert me with any untrusted connection message. This continues and is not your staff websecurity/firewall, please check again resolve the error message "secure connection failed" and come up with an answer so we can continue to troubleshoot.

• Message "this connection is not approved" for each Web site.

  This has happened to me whenever I try to visit almost any Web site. I can't visit the Web site because the connection is 'Untrusted' and site identity 'cannot be verified. This happens with popular sites such as Google, Bing, Youtube, etc. What should I do?

  If parental control is proving to be the question, please see this thread for how to configure Firefox to work with the program: Firefox has issues with the security certificates for yahoo and google when my son connects like a child under one account in windows 10 family.

• I get a message that says: "this connection is not approved" whenever I try to access ANY Web site

  I looked through previous questions and remove any software suspicious (it was not really, just a Bing bar). I deleted firefox and reloaded it. I bought Norton Antivirus and ran a scan - nothing. Date and time on my computer are correct. Explorer works very well. Help! I prefer firefox, but I can't access ANY Web site. I get this message every time.

  I've been down all the instructions on the Firefox support forum, and nothing has worked. The question may not be the Web site certificate, because it happens to EVERY SINGLE website I try to access. Nevertheless, I have add an exception for Facebook according to the instructions. That caused a strange page, not formatted to come. Since, I have read that to make an exception is dangerous because it can cause MORE unwanted malware to infect the computer.

  However, I did figure it out on my own so maybe this will help those who are facing this problem in the future: after reading the past messages from those who have experienced the same thing, I realized that, in all cases, the solution was to remove some kind of unwanted software (malware). I'm very careful NOT to download the software and I noticed that another victim of this says the same thing, so it's sneaky. I even bought new software (Norton) antivirus, performed a scan and the problem has not been found.

  I went to programs "to uninstall programs," sorted by date and anything that looked suspicious that was recently removed. I had something with the word "rocket" in it. It looked like a game. There is also another program that I removed (don't remember the name of it now). Removing those does not solve the problem, so I returned through all programs on my list and removed something that said "toolbar" on this topic, even if it was reliable (I had a bing and google toolbar). That doesn't seem to work either so I sort the programs by date again and I noticed that the software "rocket" was ALWAYS THERE.

  I have a click with the right on it and then click on 'uninstall' button again. It takes unusually LONG for this program uninstall AND nothing appears on the screen. The computer has just sort of is there and does nothing. I left and when I came back (about an hour later) the program had disappeared from the list.

  Firefox now works. I no longer receive this message, but here's the deal: I'm not 100% sure what program was the problem. It was this software of rocket or one of the toolbars. Nevertheless, the answer always seems to be some kind of unwanted malware, so I recommend that any victim of this problem try to uninstall the suspicious programs initially. And this means that ALL suspicious programs are RECENT, regardless of if they resemble games or antivirus or another. If it is new and you do not download it, uninstall it.

• How can I disable the warning "this connection is not approved", which appears almost each time I try to go to a Web page via Firefox? I use 10 64-bit Windows.

  I just upgraded to 10 64-bit Windows. The version of Firefox that works now on this OS regularly displays a blocking window that told me that "this connection is not approved" when I try to connect to a third-party site. A screenshot of the window copy is attached. How to disable this warning? I can't continue to use Firefox if I can't find the 'off' switch, which so far has escaped me.

  Yes, this is the feature, and it is lit.

  How it works, is that ESET intercepts all your browser connections to filter the content. If it is an HTTP connection, it is transparent. For an HTTPS connection, ESET must present a certificate of 'false' for Firefox site so it can be the "man in the middle" and decipher and read the answer (otherwise, it's gibberish, of course).

  ESET is supposed to insert his signature certificate in both the Windows certificate store (used by IE and Chrome) separated from Firefox AND the browser certificate store accepts the false certificates. But it does not always work. In this case, you can import the certificate manually in Firefox. If all goes well, which has been covered in the manual, but otherwise it's basically along these lines:

  (1) search or save a copy of the ESET signature certificate (it is a file in DER format that usually has the .cer extension). Is your second screen shot what appears when you click View Certificate? Try this:

  • Click the Details tab, click the button "Copy to File. This will start the Export Wizard.
  • In the wizard, choose the DER format and save in a suitable location (for example, your Documents folder).

  (2) import the file into Firefox as follows:

  • In Firefox, open the Certificate Manager to:
    "3-bar" menu button (or tools) > Options > advanced > mini-onglet Certificates > "view certificates" button.
  • Click on mini - the References tab, then on the 'Import' button and find the DER file. Note: I suggest allowing the certificate for websites only.

  I have attached a few screenshots of reference sample.

• "This connection is Untrusted" appears when you try to access all sites on MacBook Pro; problem started after running Avast scan of the computer

  I ran the full scan of the disc of Avast. Since then, I have been unable to access any site using Firefox without getting the message, "this connection is not approved." Many are the sites I have been too many times before, and they are trusted sites. I don't know if there is a problem with Firefox or Firefox could recover place a sort of new "infestation". The Avast scan resulted in 5 put files in a quarantine area. Eleven years could not be scanned. Thanks for any help you can provide!

  I guess Safari normally works on these sites?

  The latest version of avast! Web Shield includes a function to filter your Internet connections for potential threats. In order to filter secure sites, it must present a certificate of 'false' for the site in Firefox, so it can be 'in the middle' and read your secure communications. If Firefox is not set false certificates of trust, then you will get warnings for all secure sites.

  You can disable this feature as a test to see if the problem goes away.

  If this works, but you want to use the feature, you must import the certificate of Avast in the tab "References" of Firefox so Firefox accepts its false certificates (there might be an automated way AVAST to do this for you, or you might need export from IE and then import them into Firefox).

  Here is an exchange of views on avast! "forum of s on the way in which this is supposed to work: problems and questions about HTTPS scanning - Avast Internet 2015

  I keep getting the "this connection is not approved" in all the sites when I use Firefox on windows laptop 36.0.1 8. How can I overcome this.

  Hi vijaysampath, please make sure first that the date, time, and time zone are set correctly on your system. If this does not solve the problem (or it is already set correctly), a possible solution depends on different factors:

  • What is the error code indicated under Technical Details on the error page?

  in case the error code is equal to sec_error_unknown_issuer, please try to add an exception on the bottom of the error page to verify the certificate, as shown on the attached screenshot:

  • What information about the issuer of the certificate contain?

  Please take these two pieces of information. Thank you!

• "This connection is not approved" message on many (most?) sites (including some Mozilla) with V16.0.1.

  "This connection is not approved.

  This message appears with most of the sites and links since I updated Firefox. This includes fundamental links concerning the resolution of items such as the SSL test and other links "try this" on the troubleshooting page. I NOD antivirus and firewall is enabled and have no problem with other search engines (Explorer and Chrome). I love Mozilla and don't want to abandon it. Help, please.
  Facebook has been the first, but they are too numerous to list.

• This connection is not approved will appear in searches

  "This connection is not approved" window appears in all the research and when I click on Add - ons to find Add-ons. Ver.39.0.

  Apparently, a new certificate of Firefox should be installed.

• Ignore the page "this connection is not approved" - no time no question

  My apologies if this has already been answered, but when I search almost all solutions are supposed to check your system time or run anti-malware software. I'm almost certain that this has nothing to do with the time system and moderately sure isn't because of malware.

  When I'm on the corporate network, I have to constantly go through the page "this connection is not approved" and go through the steps starting with "I understand the risks". When I look at the certificate, it looks like, it is delivered by our company IT Department. For me, that's good, because the pages that I'm going to are not sensitive for me.

  For example, when I go to http://google.com, for some reason any it redirects to https. Even if I think it's nice that google is on the lookout for me and a encrypting my traffic, it becomes annoying to many mouse clicks in firefox to do a simple google search to do my job.

  You must request the certificate root of the proxy server used by your corporate network to connect to the internet.

• I went from a Win7 32-bit on a 64-bit win7 machine computer. Now, I get "this connection is not approved" any solution? tried everything

Now, I get "this connection is not approved" on many pages, including support for Mozilla, Yahoo, send a mail to yahoo, etc. The only thing that has changed is my computer. Everything worked on the 32-bit system. I tried DELL-no-help, I tried Norton-no-help - I tried all published recommendations - nothing helped. Can someone give an explanation of how solve this incompatibility (presumed) Win7 64 bit computers? How can I quickly and absolutely get rid of MESSAGES "THIS CONNECTION IS UNTRUSTED"?
  Thanks for ANY help from an expert.

  Right after that I posted this problem it seemed the solution:
  I noticed a pop-up, named "BROWSERSAFEGUARD" who has attempted to set my computer to a "cleaner" for a price. I checked in my installed programs if there was a "Browsersafeguard" and he was there. I uninstalled it, check "incompatible with my system" and my computer turned on like never before. Lightning fast connections and no message more "this connection is not approved. Wow. It took me 7 days to find it. Hope this will help you, too. Send a message to this one to let me know if it solved your problem

• How to disable "this connection is not approved?

  I just installed a cost of windows xp on my pc and I use the 26.0 last FF, but early on, I can't to certain pages, as in youtube, does a few pages and I get page "this connection is not approved", in technical details, it says"youtube.com uses an invalid security certificate, the certificate is not reliable because no transmitter channels are provided.

  also, when I opened FF modules manager Extensions tab, appearance, Plugins and Services are ok but the tab modules get does not work, I get the same page I mentioned above with the same technical details (instead of youtube.com is services.addons.mozilla.org) and the same error.
  I tried all the solutions on the web and on this forum as reset FF, set the time / date, using the add-on 'Ignore the cert error', delete the file cert8.db and so on--none of them helped me with this problem.
  If it helps I use Avast! antivirus and Firewall window, no other software on this computer.

  • https://support.Mozilla.org/KB/secure+connection+failed

  You can retrieve the certificate and check details such as WHO issued the certificates and the expiration dates of certificates.

  • Click on the link at the bottom of the error page: "I understand the risks".

  Let Firefox recover the certificate: "Add Exception"-> "get certificate".

  • Click on the "view..." button. "and inspect the certificate and the Coachman, who is the issuer of the certificate.

  You can see more details like the intermediate certificates that are used in the details pane.

  If "I understand the risks" is missing, this page can be opened in a (i) frame and in this case, try the shortcut menu and use "Frame this: Open image in New Tab".

  Note that some firewall monitors connections (sure) and that programs like Sendori or Fiddler (FiddlerRoot) can intercept connections and send their own certificate instead of the certificate of the Web site.

  If the problem persists, you can also consider the function of Reset Firefox via help (Alt + H) > troubleshooting information.

  (To return to the previous mode, you were using, close the new profile (i.e. Quit Firefox), start Firefox and choose the default user profile.) Alors_que Profile Manager is open, you can also remove the reset your profile (the one containing the random numbers) or the old profile, as appropriate). If the reset is correct, it would be a good idea to delete the old profile as otherwise it would be left intact with the previous data before deletion.
