I have tried to add an exception via about:config.....it is not available. This is a site that I visit daily and must use chrome.

How do i make a permanent exception? Firefox 37.0.1

Thgank you

After my firefox updated to last version (37.0.1), i can not browse my Bizchannel CIMB

URL : https://bizchannel.cimbniaga.co.id/corp/common2/login.do?action=loginRequest

withe following error : An error occurred during a connection to bizchannel.cimbniaga.co.id. Cannot communicate securely with peer: no common encryption algorithm(s). (Error code: ssl_error_no_cypher_overlap)

What should i do ?

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 :)

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.

I'm using Firefox 38.5 on CentOS 5.6. My current settings in about:config are as follows: security.tls.version.fallback-limit = 3 security.tls.version.max = 3 security.tls.version.min = 1

Are these settings already correct to only allow tls 1.2 or do I need to change the min value to 3 as well?

Microsoft just updated and now Firefox will not let me open up any web sites, except yours. It will not even let me open my Star One Credit Union account saying it is unsecured. I clicked the box that said exception and now it allows me to open this. However, there are still many sites it will not let me access without declaring an exception. I like the fact that Firefox will notify me of unsecured sites, but since it seems to think every site is improperly set up, how do I know which sites are ok and which are not?

Hi. I'm trying to log on to a particular company's website and keep getting the message :

"The requested URL was rejected. Please consult with your administrator. Your support ID is: 11373612934950299921" (with a different number each time)

I've cleared my histories, cache and cookies. My Firefox updates itself.

Going to other sites is fine.

I've spoken to the company, they don't know what's happened and are not having this problem themselves or with any other customers.

Which administrator might it be referring to? Can anyone help? (I'm not sure whether to click on 'Share Data' below; let me know if this would be helpful.) Many thanks.

I got "Secure Connection Failed, The connection to the server was reset while the page was loading. 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." message when I go to the site "https://gearup.ed.gov/". I checked my server is set up TLS 1.2

I am using Firefox 62, in my SSLtest, I got "Firefox 62 / Win 7 R Server closed connection" https://www.ssllabs.com/ssltest/analyze.html?d=gearup.ed.gov

Does anyone how to fix that issue? Thanks

Whenever I visit a website that has an SSL certificate issue, instead of any kind of actual error page, Firefox just shows a modal "Alert" dialog box with no text.

In the attached screenshot, I visited a page I know has an SSL certificate issue. In Chrome, I get a full-page warning. But in Firefox, just the description-less "Alert" box.

I tried disabling all of my plugins before visiting the site as well and got the same result. I don't seem to have customized any of the SSL or Certificate settings in about:config either.

Does anybody have any idea how I can get something approaching normal behaviour out of Firefox for mac?

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 need to access a router that has only https interface.

After updating to FireFox 63.0 I can no longer access the device and there appears no obvious way to convince FireFox to connect.

Please advise

As of this morning, I am unable to access many of the sites I visit regularly and am now unable to conduct aspects of my business. The error is always that the connection timed out, the website isn't available and the tls handshake simply stops.

I can't even reach https://input.mozilla.org/en-US/feedback/firefox/67.0/ because of this handshake. That's kind of ridiculous, isn't it?

The issue doesn't affect all websites, but unfortunately it's the ones I need. I've created a new profile, refreshed Firefox, reset my modem and router. My ISP says the connection is fine on their end.

Firefox is the only browser I have access to on my desktop. Google Chrome, which I don't want to use, works fine on my Android phone.

Hi - I recently deleted SSLs from two of my websites and whislt doing so took all necessary steps to forced HTTP not HTTPS. The sites: 15rueduvieilhopital.fr & thetallskinnylattephilosopher.com load in all browsers and on all devices ok EXCEPT FF on my desktop (v69.0.3 on Mac OS 10.14.6) which keeps looking for the SSl and, because it can't find one, generates a security warning. For the record this doesn't happen in a private browsing window in FF. It appears that FF is somehow caching the SSL. I have deleted 'Everything' from my history and quite and restarted FF but the probelm perists.

Can anyone tell me how to remove the SSLs from the cache?

Thanks Martin

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 :)
