Firefox Support Forum

Since upgrading to firefox 50.0.1 I cannot do a search with Google (or any other engine) search. I get "Your connection is not secure". Everything works with Chrome and Safari. I have a MACBook Pro OSX 10.12.1 with no antivirus. Firefox is set up to ignore IVP6 and I have no proxy. I can't even run the "SSL Labs' test page" as suggested by the Mozilla help pages. What is going on? What is stopping searches. I can browse other pages without a problem. thanks for any help.

I keep getting this error on multiple sites. It makes it nearly impossible to search. Here is the log. https://www.google.com/search?q=lokl&ie=utf-8&oe=utf-8

Hello, friends, I hope you all doing great. My english is really bad, so I'll go straight to the problem: I can't access Google.com or any Google site on Firefox.

The message:

Hello

I have had this issue for 3 days now. I am unable to access yahoo mail or yahoo in general because I get warning potential risk ahead message. I had to make twitter account to be able to get in touch with yahoo support but they just offered a yahoo link which, of course, I am unable to open because of "potential risk ahead". I tried solutions suggested by people here at mozilla support, like clearing history, cache etc but it didn't work. I also tired accessing yahoo via internet explorer and chrome (installed on my father's laptop, windows 10) Of course same message appears. I am using windows 7 64 bit. I also tried Edge and of course it says yahoo site is not secure. I have never had these kind of problems before. I was always able to access yahoo via FIrefox and other browsers. It's really damn annoying because i see no solution to this damn crap. Also I am unable to upload a 170kb screenshot to show you the issue. Just keeps loading and loading and it doesn't stop. So I guess I will just have to describe it:

Firefox detected a potential security threat and did not continue to guce.yahoo.com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for guce.yahoo.com. The certificate is only valid for *.amz-aws.jp. Error code: SSL_ERROR_BAD_CERT_DOMAIN

https://guce.yahoo.com/consent?gcrumb=gscOGxw&trapType=login&done=https%3A%2F%2Fwww.yahoo.com%2F&src= Unable to communicate securely with peer: requested domain name does not match the server’s certificate. HTTP Strict Transport Security: false HTTP Public Key Pinning: false

I've been using hushmail.com for years. All of a sudden, just now, firefox is saying its insecure:

"secure.hushmail.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 "

I easily accessed hushmail in safari. I'm signed in right now.

Any issues with me making an exception?

Hi,

I get this error message when I try connecting to Netflix and some other sites such as Origin when I am connected to a WiFI:

Your connection is not secure

The owner of www.netflix.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

www.netflix.com uses an invalid security certificate.

The certificate is not trusted because it is self-signed. The certificate is only valid for .

Error code: MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT

HOWEVER, the sites work fine when I plug in my phone and use it's hotspot data. Any ideas? I've been trying for weeks, thanks.

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.

I connect to internal systems frequently and that have private certs. I just want to auto add an exception and avoid multiple clicks to get to the actual page. I do not see a way to do this but am hoping for a less documented feature.

Thanks!

i use a wifi connection offered by my landlord that requires a log in process. it includes a Dell firewall. the certificate is considered unsafe by Mozilla. Mozilla allows me to add an exception, and the window that comes up has an option to make the exception permanent, but it wont allow me to check the box to make it permanent. it would make things easier if i could make the exception permanent. how do i make this certificate a permanent exception? thank you for your time in this matter, and have a great day!

I just made my website and it's not working in Firefox however in chrome its working fine. It's in Wordpress. Is something wrong with my wordpress plugins.

It gives me error that says "Secure Connection Failed"

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.

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.

I'm still getting the "Secure Connection Failed" error on various sites.

Only in Firefox. Internet Explorer and Chrome both load the sites correctly.

Dear Firefox community, with v66.0.3 on MacOS I suddenly can no longer load this page:

   https://wiki.egi.eu/

With older versions I had no problem for that page and it still loads fine e.g. in Safari. It uses a certificate from a certificate authority that is fine for the intended audience of that service. The error page does not even give me an option e.g. to add an exception for that page, FF just refuses to go there (see image).

One particular web site won't load, and I was previously able to view the site roughly 2 weeks ago. It's a free WordPress site/blog.

I keep getting the error message "The connection to the server was reset while the page was loading." I've tried deleting all cookies and emptying the cache with no success. I also tried a "DNS Flusher" with the same result.

I've followed all the recommendations on the Firefox Help link and checked the Community and FAQ sections with no luck.

I can view the page in Safari. The web site owner can view the web site using a setup similar to mine (Mac OS 10.5, Firefox 12.0).

Nothing I know have has changed since I was able to view the site 2 weeks ago i.e., I'm not going through a proxy server nor do I have any secondary security or anti-virus programs running.

Any help would be appreciated.

I'm not great with computers, so please help me if anyone can. I've been searching for a solution for 5 hours now and I'm desperate...

My Firefox has been running a little slow the last couple of days, and sometimes temporarily stops working a couple of seconds when I'm trying to load a page. So I tried to refresh firefox through the Troubleshooting-page. After doing that, I was gonna reinstall my Addblock Plus, but when visiting about:addons, the page looked weird. The text was all in the Time New Roman-font, and there were no pictures. It was like the page hadn't loaded properly. I refreshed Firefox again, but this time I deleted all Cache and Cookies and the saved internet information. But the problem remained. I tried to install Adblock anyway, but it didn't work.

I then uninstalled Firefox from the computer and downloaded the latest version. The problem still remained.

I was now suspecting that maybe I had picked up some nasty virus or something, so I reset the computer two weeks to a date where I was pretty sure it didn't have these problems. But instead of solving my problem, it gave me another one: I couldn't access Twitter. According to Firefox, the certificate wasn't correct and the only option available was "Get me out of here". The technical information said that this was the problem: sec_error_unknown_issuer

At one point, even Google got the same certificate error, and another time I could access Twitter, but it was in the same "Times New Roman"-view with only basic text and no images. And ALL Firefox related pages were like that too.

I have temporarily fixed the problem by asking my antivirus software (ESET NOD 32) to deactivate its HTTP Control, but that doesn't seem like a safe solution to me. I'd just like to know WHAT THE HECK is going on, and how can I properly fix this?

Info: -I'm using Windows 7

I have tried: -Deleting all Cache and Cookies (together with all other internet history) -Refreshing Firefox -Uninstalling and re-installing Firefox -Deleting the Cert8 file -Restarting the computer (multiple times) -Scanning my computer for virus (Using ESET NOD32)

I don't understand what could cause Firefox to not being able to load its own sites properly... Or why Google and Twitter's certificates suddenly stopped working after reinstalling Firefox. Any ideas or help are appreciated. Especially if you keep it simple, since I'm not awesome at computers and English is not my native language .

Hi all, When I turn OCSP stapling on because of certificate transparency, I'm getting this error message in Firefox (v66.0.5):

Any ideas, where should be an issue ? I can turn off ocsp stapling in about:config: security.ssl.enable_ocsp_stapling;false and page works fine then, but site has lot off customers, so this is not relevant solution for me.

Thank you for all your hints...
