Hi there,

I'm trying to disable insecure ciphers in TLS 1.2 since 1.3 isn't widely supported yet.

I'm using this to determine whats secure: https://browserleaks.com/ssl

I cant find any option to disable these two ciphers:

0x009c TLS_RSA_WITH_AES_128_GCM_SHA256 0x009d TLS_RSA_WITH_AES_256_GCM_SHA384

Thanks :)

Since upgrading to version 37.0.1 I am no longer able to access any SSL site not even https://support.mozilla.org! Please see attached for the error message.

I have tried the following articles without any success:

https://support.mozilla.org/en-US/questions/1035913 https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can

I can't find any other articles on https://support.mozilla.org. PS I had to log this ticket using Google Chrome as I am not able to access your site as it uses SSL.

I am sure this is probably a simple issue but would appreciate your help on this.

Thanks

6:43 PM 4/24/2015 Compatible issues firefox v37.0.2 with att yahoo mail

Hello: this is my first post,hope I am doing it properly. I am using W7pro OS and ATT DSL 3.0Mbps dl I noticed this week that I was unable to save attachments from my ATT Yahoo mail I could view them but no choice as to ware to save them--only choice (save to my comp.)But no ware to be found. I reinstalled v 36.0.4-preventing auto upgrade-But still had same problem. At this point contacted ATT support supervisor-we spent about 4hr working on problem--He was using your v 31.5.0--and had no problem accessing and saving attachments using remolt access on my comp. We also found using my comp.FF v 36.0.4 & v 37.0.2 browser,that we could without any problems access an save attachments--AOL mail-- & mail2web.--& IE--Even when forwarding inaccessible mail to above sites.

He informed me that (ATT mail Yahoo)only uses resources to make them compatible with--Google IE & Chrome &Apple? (basically he was saying,that they would NOT commit resources to FF--any version)BUT he was not allowed to commit.


PS: The last time I know it worked ok was 3-18-15 I have 3 comp.2 wxp pro 1 w7 pro the same problem on all 3--so feel confident not OS related-but compatible problems with FF & yahoo mail.

The ATT support supervisor-was unable to determined the date they may have made changes on their site.without extensive research-which we decided wasn't worth the effort as they wouldn't look in to it.

I hope someone or FF will be able find a workaround-as I do not want to use the browsers they suggest. I LOVE FF.

Thank You Gary

I have some panicked people in my office, so I decided to go the source. "They" heard... I do not know where... that Firefox's next update would block ALL SSL, therefore any website we need to log into will be blocked. From what I can see on this support site, nothing is coming that is different from what happened in December 2014 in response to Poodle with the SSLv.3.

I need to settle the ruffled feathers: will Firefox still work with SSL in the future?

Thank you very much for your time :)

Hello.

I'm trying to do some online shopping, and I see the green padlock on my screen and everything, but I'm still not sure if I have a secure internet connection. The following is what Firefox says the encryption is.

(TLS_RSA_WITH_AES_128_CBC_SHA, 128 bit keys)

With the latest update access to all Cisco devices via FireFox is no longer supported. I am now receiving the following errors:

Secure Connection Failed An error occurred during a connection to [IP]. SSL received a weak ephemeral Diffie-Hellman key in Server Key Exchange handshake message. (Error code: ssl_error_weak_server_ephemeral_dh_key) The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem.

Is there a way to roll-back the version to avoid this or a permanent fix? FireFox is currently the only browser that works very well with Cisco devices and now it will not work at all.

в последнее время при попытке входа на сайты, с защищенным соединением, начала вылазить ошибка:Ошибка при установлении защищённого соединения

При соединении с имя_сайта произошла ошибка. Алгоритм подписи в поле подписи сертификата не соответствует алгоритму в его поле signatureAlgorithm. (Код ошибки: mozilla_pkix_error_signature_algorithm_mismatch). например, на таком известном как ru.wikipedia.org. В то-же время, Хром прекрасно ходит по всем тем сайтам, куда невозможно зайти через мозилу. Долгое время пользовался этим браузером и, несмотря на то что он иногда зависает и постоянно отваливается плагин Adobe Flash, уходить с него не хотелось-бы.

I am a medical insurance biller. I downloaded Windows 8, and Mozilla Firefox so that I could use United Healthcare Authorizations because they stopped allowing use on Google Chrome. I tried to get on the site, and the message I received was:

"An error occurred during a connection to saml2.radiologynotifications.com. SSL received a weak ephemeral Diffie-Hellman key in Server Key Exchange handshake message. (Error code: ssl_error_weak_server_ephemeral_dh_key)

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem."  

When I looked this up, it said that your site said this was a malicious site and blocked it. This is a secure site. And I need this site for my work. I have been doing this for 15 years, and If I cannot use this I will be forced to use another browser.

Can you please help me?
