I have imported every **** certificate from internet explorer and google chrome in the most ridiculous tedious manner possible and still can't access google.com. I can access amazon, gitlab, and other websites just fine but google.com is a no go.

I get the following error after hitting the advanced button... www.google.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported. Error code: SEC_ERROR_UNKNOWN_ISSUER

Furthermore here is the SEC_ERROR_UNKNOWN_ISSUER... https://www.google.com/search?q=amazon&ie=utf-8&oe=utf-8&client=firefox-b-ab

I'm losing my mind over this so if you would be so kind to provide detailed and direct fixes to this issue that will resolve the error it will be much appreciated. If there is any more information I need to give you please indicate that.

Really? Amazon's website is insecure? You need to look into why you won't let users go there.

Firefox won't let me access Amazon's website. Need to use Chrome. Where do you suppose is the problem, with Amazon or with Firefox?

I cannot get to Citibank on FireFox. Chrome & Internet Explorer OK. This problen started about a week ago.

Typing in all variations of Citibank tells me that the server does not exist. I have been using Firefox for years to get to Citibank.

Hello,

I see that mistake via https://lenuar.com.ua/ but here are my SSL certificate details: https://decoder.link/sslchecker/lenuar.com.ua/443 As you see, OCSP Responder returned "good" status for the end-entity certificate. So I have no idea what is the issue with this certificate and how to resolve it.

No matter which website I try recently I keep getting "Your connection is not secure" and Error code: SEC_ERROR_UNKNOWN_ISSUER Other web browsers work fine. I tried disabling Avira and have Firefox in my list of Windows firewall exceptions but the problem was not solved. Below is a dump of the error messages. Let me know what I can do to fix this issue once and for all. I am running Windows 10 and using Firefox 60.0.1 (64-bit)

I've always been able to donate to charities fairly easily online, but keep getting the "insecure host" message. Surely these are well-known charities that presumably run secure websites. I now have FSecure to protect my laptop and phone; could it be that? My brother says I need someting like FSecure, my son says Firefox alone should be enough. Don't know! Thanks S Peach (UK)

FF version 59.0.3 kaspersky internet security suite

of late, when a new version of firefox comes out they break something.

i am seriously thinking of chrome - heaven's forbid - but at least it works.

so any help to resolve this issue would be great before i enter the evil chrome empire :-(

since firefox updated to the above version i get the following error messages on some major websites, like bbc.co.uk, wikipedia, and others, some websites work, i have added some as exclusion but other websites don't give me the option.

the websites work in the Edge browsers ok.

some website sort of work, they just display strangely, mainly text and very little formatting at that.

i have set kaspersky to not scan encrypted connections in the network section, but that stop the mymoney protected browser from kaspersky from working!

i seem to spend more time getting firefox to work after an update, i'm at the point now where i just can't be bothered anymore.

i have cleared caches and other things i have seen as suggested fixes.


firefox states...

The owner of en.wikipedia.org has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

the advanced tab displays

The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported.

So basically, Iv been trying to access steam & thesimsresource but weirdly an error message comes up It looks like this:

Unable to connect

Firefox can’t establish a connection to the server at www.thesimsresource.com.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

Im really confused as this has never happened before. If you have an answer to my problem please explain in a simple way as all this is extremely complicated.

All websites are giving me an error. City & state governments and websites I used yesterday, etc.

I don't want to do anything foolish, but this has become tedious.

I have none of the AVs listed in your instructions and Avira never presented problems before.

This is just one example: budget.weho.org uses an invalid security certificate. The certificate is only valid for the following names: *.herokuapp.com, herokuapp.com Error code: SSL_ERROR_BAD_CERT_DOMAIN

Problem with 'require safe negotiation'

I tried to make a purchase and during one of the redirects Firefox reported that it was unable to establish safe negotiation (error code: SSL_ERROR_UNSAFE_NEGOTIATION). The site that had the problem is https://secure5.arcot.com/ . I have security.ssl.require_safe_negotiation set to true. However, if I set it to false and go to that site, Firefox reports that it uses "TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, 256 bit keys, TLS 1.2". I am not an expert in ciphers/TLS but the version seems sufficiently new.

I would like to report the problem but I need to know whom to report it. So far, it seems like a Firefox bug. However, I am not a security expect and, perhaps, the site is using a different obsolete SSL version to negotiate. How can I determine what exactly caused the failure?
